/**
 * @ngdoc service
 * @name $mdCompiler
 * @module material.core.compiler
 * @description
 * The $mdCompiler service is an abstraction of AngularJS's compiler, that allows developers
 * to easily compile an element with options like in a Directive Definition Object.
 *
 * > The compiler powers a lot of components inside of AngularJS Material.
 * > Like the `$mdPanel` or `$mdDialog`.
 *
 * @usage
 *
 * Basic Usage with a template
 *
 * <hljs lang="js">
 *   $mdCompiler.compile({
 *     templateUrl: 'modal.html',
 *     controller: 'ModalCtrl',
 *     locals: {
 *       modal: myModalInstance;
 *     }
 *   }).then(function (compileData) {
 *     compileData.element; // Compiled DOM element
 *     compileData.link(myScope); // Instantiate controller and link element to scope.
 *   });
 * </hljs>
 *
 * Example with a content element
 *
 * <hljs lang="js">
 *
 *   // Create a virtual element and link it manually.
 *   // The compiler doesn't need to recompile the element each time.
 *   var myElement = $compile('<span>Test</span>')(myScope);
 *
 *   $mdCompiler.compile({
 *     contentElement: myElement
 *   }).then(function (compileData) {
 *     compileData.element // Content Element (same as above)
 *     compileData.link // This does nothing when using a contentElement.
 *   });
 * </hljs>
 *
 * > Content Element is a significant performance improvement when the developer already knows that the
 * > compiled element will be always the same and the scope will not change either.
 *
 * The `contentElement` option also supports DOM elements which will be temporary removed and restored
 * at its old position.
 *
 * <hljs lang="js">
 *   var domElement = document.querySelector('#myElement');
 *
 *   $mdCompiler.compile({
 *     contentElement: myElement
 *   }).then(function (compileData) {
 *     compileData.element // Content Element (same as above)
 *     compileData.link // This does nothing when using a contentElement.
 *   });
 * </hljs>
 *
 * The `$mdCompiler` can also query for the element in the DOM itself.
 *
 * <hljs lang="js">
 *   $mdCompiler.compile({
 *     contentElement: '#myElement'
 *   }).then(function (compileData) {
 *     compileData.element // Content Element (same as above)
 *     compileData.link // This does nothing when using a contentElement.
 *   });

   *
   * @description
   * Call this method to enable/disable whether Material-specific (dialogs/toasts) controllers respect the AngularJS
   * `$compile.preAssignBindingsEnabled` flag. Note that this doesn't affect directives/components created via
   * regular AngularJS methods which constitute most Material & user-created components.
   *
   * @see [AngularJS documentation for `$compile.preAssignBindingsEnabled`
   * ](https://code.angularjs.org/1.6.4/docs/api/ng/provider/$compileProvider#preAssignBindingsEnabled)
   * for more information.
   *
   * If disabled (false), the compiler assigns the value of each of the bindings to the
   * properties of the controller object before the constructor of this object is called.
   *
   * If enabled (true) the behavior depends on the AngularJS version used:
   *
   *     - `<1.5.10` - bindings are pre-assigned
   *     - `>=1.5.10 <1.7` - behaves like set to whatever `$compileProvider.preAssignBindingsEnabled()` reports; if
   *                         the `$compileProvider` flag wasn't set manually, it defaults to pre-assigning bindings
   *                         with AngularJS `1.5.x` & to calling the constructor first with AngularJS `1.6.x`.
   *     - `>=1.7` - the compiler calls the constructor first before assigning bindings
   *
   * The default value is `false` but will change to `true` in AngularJS Material 1.2.
   *
   * It is recommended to set this flag to `true` in AngularJS Material 1.1.x; the only reason it's not set that way
   * by default is backwards compatibility. Not setting the flag to `true` when
   * `$compileProvider.preAssignBindingsEnabled()` is set to `false` (i.e. default behavior in AngularJS 1.6.0 or newer)
   * makes it hard to unit test Material Dialog/Toast controllers using the `$controller` helper as it always follows
   * the `$compileProvider.preAssignBindingsEnabled()` value.

   *
   * A method to compile a HTML template with the AngularJS compiler.
   * The `$mdCompiler` is wrapper around the AngularJS compiler and provides extra functionality
   * like controller instantiation or async resolves.
   *
   * @param {!Object} options An options object, with the following properties:
   *
   *    - `controller` - `{string|Function}` Controller fn that should be associated with
   *         newly created scope or the name of a registered controller if passed as a string.
   *    - `controllerAs` - `{string=}` A controller alias name. If present the controller will be
   *         published to scope under the `controllerAs` name.
   *    - `contentElement` - `{string|Element}`: Instead of using a template, which will be
   *         compiled each time, you can also use a DOM element.<br/>
   *    - `template` - `{string=}` An html template as a string.
   *    - `templateUrl` - `{string=}` A path to an html template.
   *    - `transformTemplate` - `{function(template)=}` A function which transforms the template after
   *        it is loaded. It will be given the template string as a parameter, and should
   *        return a a new string representing the transformed template.
   *    - `resolve` - `{Object.<string, function>=}` - An optional map of dependencies which should
   *        be injected into the controller. If any of these dependencies are promises, the compiler
   *        will wait for them all to be resolved, or if one is rejected before the controller is
   *        instantiated `compile()` will fail..
   *      * `key` - `{string}`: a name of a dependency to be injected into the controller.
   *      * `factory` - `{string|function}`: If `string` then it is an alias for a service.
   *        Otherwise if function, then it is injected and the return value is treated as the
   *        dependency. If the result is a promise, it is resolved before its value is
   *        injected into the controller.
   *
   * @returns {Object} promise A promise, which will be resolved with a `compileData` object.
   * `compileData` has the following properties:
   *
   *   - `element` - `{element}`: an uncompiled element matching the provided template.
   *   - `link` - `{function(scope)}`: A link function, which, when called, will compile
   *     the element and instantiate the provided controller (if given).
   *   - `locals` - `{object}`: The locals which will be passed into the controller once `link` is
   *     called. If `bindToController` is true, they will be coppied to the ctrl instead

/**
 * @ngdoc service
 * @name $mdThemingProvider
 * @module material.core.theming
 *
 * @description Provider to configure the `$mdTheming` service.
 *
 * ### Default Theme
 * The `$mdThemingProvider` uses by default the following theme configuration:
 *
 * - Primary Palette: `Blue`
 * - Accent Palette: `Pink`
 * - Warn Palette: `Deep-Orange`
 * - Background Palette: `Grey`
 *
 * If you don't want to use the `md-theme` directive on the elements itself, you may want to overwrite
 * the default theme.<br/>
 * This can be done by using the following markup.
 *
 * <hljs lang="js">
 *   myAppModule.config(function($mdThemingProvider) {
 *     $mdThemingProvider
 *       .theme('default')
 *       .primaryPalette('blue')
 *       .accentPalette('teal')
 *       .warnPalette('red')
 *       .backgroundPalette('grey');
 *   });
 * </hljs>
 *

 * ### Dynamic Themes
 *
 * By default, if you change a theme at runtime, the `$mdTheming` service will not detect those changes.<br/>
 * If you have an application, which changes its theme on runtime, you have to enable theme watching.
 *
 * <hljs lang="js">
 *   myAppModule.config(function($mdThemingProvider) {
 *     // Enable theme watching.
 *     $mdThemingProvider.alwaysWatchTheme(true);
 *   });
 * </hljs>
 *
 * ### Custom Theme Styles
 *
 * Sometimes you may want to use your own theme styles for some custom components.<br/>
 * You are able to register your own styles by using the following markup.
 *
 * <hljs lang="js">
 *   myAppModule.config(function($mdThemingProvider) {
 *     // Register our custom stylesheet into the theming provider.
 *     $mdThemingProvider.registerStyles(STYLESHEET);
 *   });
 * </hljs>
 *
 * The `registerStyles` method only accepts strings as value, so you're actually not able to load an external
 * stylesheet file into the `$mdThemingProvider`.
 *
 * If it's necessary to load an external stylesheet, we suggest using a bundler, which supports including raw content,
 * like [raw-loader](https://github.com/webpack/raw-loader) for `webpack`.
 *
 * <hljs lang="js">
 *   myAppModule.config(function($mdThemingProvider) {
 *     // Register your custom stylesheet into the theming provider.
 *     $mdThemingProvider.registerStyles(require('../styles/my-component.theme.css'));
 *   });
 * </hljs>
 *
 * ### Browser color
 *
 * Enables browser header coloring
 * for more info please visit:
 * https://developers.google.com/web/fundamentals/design-and-ui/browser-customization/theme-color
 *
 * Options parameter: <br/>
 * `theme`   - A defined theme via `$mdThemeProvider` to use the palettes from. Default is `default` theme. <br/>
 * `palette` - Can be any one of the basic material design palettes, extended defined palettes and 'primary',
 *             'accent', 'background' and 'warn'. Default is `primary`. <br/>
 * `hue`     - The hue from the selected palette. Default is `800`<br/>
 *
 * <hljs lang="js">
 *   myAppModule.config(function($mdThemingProvider) {
 *     // Enable browser color
 *     $mdThemingProvider.enableBrowserColor({
 *       theme: 'myTheme', // Default is 'default'
 *       palette: 'accent', // Default is 'primary', any basic material palette and extended palettes are available
 *       hue: '200' // Default is '800'
 *     });

/* Some Example Valid Theming Expressions
 * =======================================
 *
 * Intention group expansion: (valid for primary, accent, warn, background)
 *
 * {{primary-100}} - grab shade 100 from the primary palette
 * {{primary-100-0.7}} - grab shade 100, apply opacity of 0.7
 * {{primary-100-contrast}} - grab shade 100's contrast color
 * {{primary-hue-1}} - grab the shade assigned to hue-1 from the primary palette
 * {{primary-hue-1-0.7}} - apply 0.7 opacity to primary-hue-1
 * {{primary-color}} - Generates .md-hue-1, .md-hue-2, .md-hue-3 with configured shades set for each hue
 * {{primary-color-0.7}} - Apply 0.7 opacity to each of the above rules
 * {{primary-contrast}} - Generates .md-hue-1, .md-hue-2, .md-hue-3 with configured contrast (ie. text) color shades set for each hue
 * {{primary-contrast-0.7}} - Apply 0.7 opacity to each of the above rules
 *
 * Foreground expansion: Applies rgba to black/white foreground text
 *
 * {{foreground-1}} - used for primary text
 * {{foreground-2}} - used for secondary text/divider
 * {{foreground-3}} - used for disabled text
 * {{foreground-4}} - used for dividers

 * section above for an example.
 *
 * Newer versions of Angular will throw a `Possibly unhandled rejection` exception if you forget
 * this.</em>
 *
 * @param {object} options An options object, with the following properties:
 *
 *   - `templateUrl` - `{string=}`: The url of an html template file that will
 *   be used as the content of the bottom sheet. Restrictions: the template must
 *   have an outer `md-bottom-sheet` element.
 *   - `template` - `{string=}`: Same as templateUrl, except this is an actual
 *   template string.
 *   - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified, it will create a new child scope.
 *     This scope will be destroyed when the bottom sheet is removed unless `preserveScope` is set to true.
 *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
 *   - `controller` - `{string=}`: The controller to associate with this bottom sheet.
 *   - `locals` - `{string=}`: An object containing key/value pairs. The keys will
 *   be used as names of values to inject into the controller. For example,
 *   `locals: {three: 3}` would inject `three` into the controller with the value
 *   of 3.
 *   - `clickOutsideToClose` - `{boolean=}`: Whether the user can click outside the bottom sheet to
 *     close it. Default true.
 *   - `bindToController` - `{boolean=}`: When set to true, the locals will be bound to the controller instance.
 *   - `disableBackdrop` - `{boolean=}`: When set to true, the bottomsheet will not show a backdrop.
 *   - `escapeToClose` - `{boolean=}`: Whether the user can press escape to close the bottom sheet.
 *     Default true.
 *   - `resolve` - `{object=}`: Similar to locals, except it takes promises as values
 *   and the bottom sheet will not open until the promises resolve.
 *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
 *   - `parent` - `{element=}`: The element to append the bottom sheet to. The `parent` may be a `function`, `string`,
 *   `object`, or null. Defaults to appending to the body of the root element (or the root element) of the application.
 *   e.g. angular.element(document.getElementById('content')) or "#content"
 *   - `disableParentScroll` - `{boolean=}`: Whether to disable scrolling while the bottom sheet is open.
 *     Default true.

 * will become a `<button>` element. As per the
 * [Material Design specifications](https://material.google.com/style/color.html#color-color-palette)
 * the FAB button background is filled with the accent color [by default]. The primary color palette
 * may be used with the `md-primary` class.
 *
 * Developers can also change the color palette of the button, by using the following classes
 * - `md-primary`
 * - `md-accent`
 * - `md-warn`
 *
 * See for example
 *
 * <hljs lang="html">

 *
 * <hljs lang="html">
 *   <md-button class="md-accent md-raised">Raised and Accent Button</md-button>
 * </hljs>
 *
 * It is also possible to disable the focus effect on the button, by using the following markup.

 *
 * @description
 *
 * The `<md-content>` directive is a container element useful for scrollable content. It achieves
 * this by setting the CSS `overflow` property to `auto` so that content can properly scroll.
 *
 * In general, `<md-content>` components are not designed to be nested inside one another. If
 * possible, it is better to make them siblings. This often results in a better user experience as
 * having nested scrollbars may confuse the user.
 *
 * ## Troubleshooting
 *
 * In some cases, you may wish to apply the `md-no-momentum` class to ensure that Safari's
 * momentum scrolling is disabled. Momentum scrolling can cause flickering issues while scrolling
 * SVG icons and some other components.
 *
 * Additionally, we now also offer the `md-no-flicker` class which can be applied to any element
 * and uses a Webkit-specific filter of `blur(0px)` that forces GPU rendering of all elements
 * inside (which eliminates the flicker on iOS devices).
 *
 * _<b>Note:</b> Forcing an element to render on the GPU can have unintended side-effects, especially
 * related to the z-index of elements. Please use with caution and only on the elements needed._
 *
 * @usage
 *
 * Add the `[layout-padding]` attribute to make the content padded.

/**
 * @ngdoc service
 * @name $mdDialog
 * @module material.components.dialog
 *
 * @description
 * `$mdDialog` opens a dialog over the app to inform users about critical information or require
 *  them to make decisions. There are two approaches for setup: a simple promise API
 *  and regular object syntax.
 *
 * ## Restrictions
 *
 * - The dialog is always given an isolate scope.
 * - The dialog's template must have an outer `<md-dialog>` element.
 *   Inside, use an `<md-dialog-content>` element for the dialog's content, and use
 *   an `<md-dialog-actions>` element for the dialog's actions.
 * - Dialogs must cover the entire application to keep interactions inside of them.
 * Use the `parent` option to change where dialogs are appended.
 *
 * ## Sizing
 * - Complex dialogs can be sized with `flex="percentage"`, i.e. `flex="66"`.
 * - Default max-width is 80% of the `rootElement` or `parent`.
 *
 * ## CSS
 * - `.md-dialog-content` - class that sets the padding on the content as the spec file
 *
 * @usage
 * <hljs lang="html">
 * <div  ng-app="demoApp" ng-controller="EmployeeController">
 *   <div>
 *     <md-button ng-click="showAlert()" class="md-raised md-warn">

 * <hljs lang="js">

 *    .module('demoApp', ['ngMaterial'])

 *         ok: 'Close'

 *            '  </md-dialog-actions>' +
 *            '</md-dialog>',
 *          locals: {
 *            items: $scope.items
 *          },
 *          controller: DialogController
 *       });
 *       function DialogController($scope, $mdDialog, items) {
 *         $scope.items = items;
 *         $scope.closeDialog = function() {
 *           $mdDialog.hide();
 *         }
 *       }
 *     }
 *   }
 * })(angular);
 * </hljs>
 *
 * ### Multiple Dialogs
 * Using the `multiple` option for the `$mdDialog` service allows developers to show multiple dialogs
 * at the same time.
 *
 * <hljs lang="js">
 *   // From plain options
 *   $mdDialog.show({
 *     multiple: true
 *   });
 *
 *   // From a dialog preset
 *   $mdDialog.show(
 *     $mdDialog
 *       .alert()
 *       .multiple(true)
 *   );
 *
 * </hljs>
 *
 * ### Pre-Rendered Dialogs
 * By using the `contentElement` option, it is possible to use an already existing element in the DOM.
 *
 * > Pre-rendered dialogs will be not linked to any scope and will not instantiate any new controller.<br/>
 * > You can manually link the elements to a scope or instantiate a controller from the template (`ng-controller`)
 *
 * <hljs lang="js">
 *   $scope.showPrerenderedDialog = function() {
 *     $mdDialog.show({
 *       contentElement: '#myStaticDialog',
 *       parent: angular.element(document.body)
 *     });
 *   };
 * </hljs>
 *
 * When using a string as value, `$mdDialog` will automatically query the DOM for the specified CSS selector.
 *
 * <hljs lang="html">
 *   <div style="visibility: hidden">
 *     <div class="md-dialog-container" id="myStaticDialog">
 *       <md-dialog>
 *         This is a pre-rendered dialog.
 *       </md-dialog>
 *     </div>
 *   </div>
 * </hljs>
 *
 * **Notice**: It is important, to use the `.md-dialog-container` as the content element, otherwise the dialog
 * will not show up.
 *
 * It also possible to use a DOM element for the `contentElement` option.
 * - `contentElement: document.querySelector('#myStaticDialog')`
 * - `contentElement: angular.element(TEMPLATE)`
 *
 * When using a `template` as content element, it will be not compiled upon open.
 * This allows you to compile the element yourself and use it each time the dialog opens.
 *
 * ### Custom Presets
 * Developers are also able to create their own preset, which can be easily used without repeating
 * their options each time.
 *
 * <hljs lang="js">
 *   $mdDialogProvider.addPreset('testPreset', {
 *     options: function() {
 *       return {
 *         template:
 *           '<md-dialog>' +
 *             'This is a custom preset' +
 *           '</md-dialog>',
 *         controllerAs: 'dialog',
 *         bindToController: true,
 *         clickOutsideToClose: true,
 *         escapeToClose: true
 *       };
 *     }
 *   });
 * </hljs>
 *
 * After you created your preset at config phase, you can easily access it.
 *
 * <hljs lang="js">
 *   $mdDialog.show(
 *     $mdDialog.testPreset()
 *   );
 * </hljs>
 *
 * ### JavaScript: promise API syntax, custom dialog template
 * <hljs lang="js">

 *   "use strict";

 *     .module('demoApp', ['ngMaterial'])

 *
 * @description
 * Show a dialog with the specified options.
 *
 * @param {object} optionsOrPreset Either provide an `$mdDialogPreset` returned from `alert()`, and
 * `confirm()`, or an options object with the following properties:
 *   - `templateUrl` - `{string=}`: The url of a template that will be used as the content
 *   of the dialog.
 *   - `template` - `{string=}`: HTML template to show in the dialog. This **must** be trusted HTML
 *      with respect to Angular's [$sce service](https://docs.angularjs.org/api/ng/service/$sce).
 *      This template should **never** be constructed with any kind of user input or user data.
 *   - `contentElement` - `{string|Element}`: Instead of using a template, which will be compiled each time a
 *     dialog opens, you can also use a DOM element.<br/>
 *     * When specifying an element, which is present on the DOM, `$mdDialog` will temporary fetch the element into
 *       the dialog and restores it at the old DOM position upon close.
 *     * When specifying a string, the string be used as a CSS selector, to lookup for the element in the DOM.
 *   - `autoWrap` - `{boolean=}`: Whether or not to automatically wrap the template with a
 *     `<md-dialog>` tag if one is not provided. Defaults to true. Can be disabled if you provide a
 *     custom dialog directive.
 *   - `targetEvent` - `{DOMClickEvent=}`: A click's event object. When passed in as an option,
 *     the location of the click will be used as the starting point for the opening animation
 *     of the the dialog.
 *   - `openFrom` - `{string|Element|object}`: The query selector, DOM element or the Rect object
 *     that is used to determine the bounds (top, left, height, width) from which the Dialog will
 *     originate.
 *   - `closeTo` - `{string|Element|object}`: The query selector, DOM element or the Rect object
 *     that is used to determine the bounds (top, left, height, width) to which the Dialog will
 *     target.
 *   - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified,
 *     it will create a new isolate scope.
 *     This scope will be destroyed when the dialog is removed unless `preserveScope` is set to true.
 *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
 *   - `disableParentScroll` - `{boolean=}`: Whether to disable scrolling while the dialog is open.
 *     Default true.
 *   - `hasBackdrop` - `{boolean=}`: Whether there should be an opaque backdrop behind the dialog.
 *     Default true.
 *   - `clickOutsideToClose` - `{boolean=}`: Whether the user can click outside the dialog to
 *     close it. Default false.
 *   - `escapeToClose` - `{boolean=}`: Whether the user can press escape to close the dialog.
 *     Default true.
 *   - `focusOnOpen` - `{boolean=}`: An option to override focus behavior on open. Only disable if
 *     focusing some other way, as focus management is required for dialogs to be accessible.
 *     Defaults to true.
 *   - `controller` - `{function|string=}`: The controller to associate with the dialog. The controller
 *     will be injected with the local `$mdDialog`, which passes along a scope for the dialog.
 *   - `locals` - `{object=}`: An object containing key/value pairs. The keys will be used as names
 *     of values to inject into the controller. For example, `locals: {three: 3}` would inject
 *     `three` into the controller, with the value 3. If `bindToController` is true, they will be
 *     copied to the controller instead.
 *   - `bindToController` - `bool`: bind the locals to the controller, instead of passing them in.
 *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
 *   - `parent` - `{element=}`: The element to append the dialog to. Defaults to appending
 *     to the root element of the application.
 *   - `onShowing` - `function(scope, element)`: Callback function used to announce the show() action is
 *     starting.
 *   - `onComplete` - `function(scope, element)`: Callback function used to announce when the show() action is
 *     finished.
 *   - `onRemoving` - `function(element, removePromise)`: Callback function used to announce the
 *      close/hide() action is starting. This allows developers to run custom animations
 *      in parallel the close animations.
 *   - `fullscreen` `{boolean=}`: An option to toggle whether the dialog should show in fullscreen
 *      or not. Defaults to `false`.
 *   - `multiple` `{boolean=}`: An option to allow this dialog to display over one that's currently open.
 * @returns {promise} A promise that can be resolved with `$mdDialog.hide()` or
 * rejected with `$mdDialog.cancel()`.

   *
   * @description
   * The `<md-fab-speed-dial>` directive is used to present a series of popup elements (usually
   * `<md-button>`s) for quick access to common actions.
   *
   * There are currently two animations available by applying one of the following classes to
   * the component:
   *
   *  - `md-fling` - The speed dial items appear from underneath the trigger and move into their
   *    appropriate positions.
   *  - `md-scale` - The speed dial items appear in their proper places by scaling from 0% to 100%.
   *
   * You may also easily position the trigger by applying one one of the following classes to the
   * `<md-fab-speed-dial>` element:
   *  - `md-fab-top-left`
   *  - `md-fab-top-right`
   *  - `md-fab-bottom-left`
   *  - `md-fab-bottom-right`
   *
   * These CSS classes use `position: absolute`, so you need to ensure that the container element
   * also uses `position: absolute` or `position: relative` in order for them to work.
   *
   * Additionally, you may use the standard `ng-mouseenter` and `ng-mouseleave` directives to
   * open or close the speed dial. However, if you wish to allow users to hover over the empty
   * space where the actions will appear, you must also add the `md-hover-full` class to the speed
   * dial element. Without this, the hover effect will only occur on top of the trigger.
   *
   * See the demos for more information.
   *
   * ## Troubleshooting
   *
   * If your speed dial shows the closing animation upon launch, you may need to use `ng-cloak` on
   * the parent container to ensure that it is only visible once ready. We have plans to remove this
   * necessity in the future.

   *
   * The `<md-fab-toolbar>` directive is used to present a toolbar of elements (usually `<md-button>`s)
   * for quick access to common actions when a floating action button is activated (via click or
   * keyboard navigation).
   *
   * You may also easily position the trigger by applying one one of the following classes to the
   * `<md-fab-toolbar>` element:
   *  - `md-fab-top-left`
   *  - `md-fab-top-right`
   *  - `md-fab-bottom-left`
   *  - `md-fab-bottom-right`
   *
   * These CSS classes use `position: absolute`, so you need to ensure that the container element
   * also uses `position: absolute` or `position: relative` in order for them to work.
   *

 * @description
 * Grid lists are an alternative to standard list views. Grid lists are distinct
 * from grids used for layouts and other visual presentations.
 *
 * A grid list is best suited to presenting a homogenous data type, typically
 * images, and is optimized for visual comprehension and differentiating between
 * like data types.
 *
 * A grid list is a continuous element consisting of tessellated, regular
 * subdivisions called cells that contain tiles (`md-grid-tile`).

 *
 * Cells are arrayed vertically and horizontally within the grid.
 *
 * Tiles hold content and can span one or more cells vertically or horizontally.
 *
 * ### Responsive Attributes
 *
 * The `md-grid-list` directive supports "responsive" attributes, which allow
 * different `md-cols`, `md-gutter` and `md-row-height` values depending on the
 * currently matching media query.
 *
 * In order to set a responsive attribute, first define the fallback value with
 * the standard attribute name, then add additional attributes with the
 * following convention: `{base-attribute-name}-{media-query-name}="{value}"`
 * (ie. `md-cols-lg="8"`)
 *
 * @param {number} md-cols Number of columns in the grid.
 * @param {string} md-row-height One of
 * <ul>
 *   <li>CSS length - Fixed height rows (eg. `8px` or `1rem`)</li>
 *   <li>`{width}:{height}` - Ratio of width to height (eg.
 *   `md-row-height="16:9"`)</li>
 *   <li>`"fit"` - Height will be determined by subdividing the available
 *   height by the number of rows</li>
 * </ul>
 * @param {string=} md-gutter The amount of space between tiles in CSS units
 *     (default 1px)
 * @param {expression=} md-on-layout Expression to evaluate after layout. Event
 *     object is available as `$event`, and contains performance information.
 *
 * @usage
 * Basic:
 * <hljs lang="html">
 * <md-grid-list md-cols="5" md-gutter="1em" md-row-height="4:3">
 *   <md-grid-tile></md-grid-tile>
 * </md-grid-list>
 * </hljs>
 *
 * Fixed-height rows:
 * <hljs lang="html">
 * <md-grid-list md-cols="4" md-row-height="200px" ...>
 *   <md-grid-tile></md-grid-tile>
 * </md-grid-list>
 * </hljs>
 *
 * Fit rows:
 * <hljs lang="html">
 * <md-grid-list md-cols="4" md-row-height="fit" style="height: 400px;" ...>
 *   <md-grid-tile></md-grid-tile>
 * </md-grid-list>
 * </hljs>
 *
 * Using responsive attributes:
 * <hljs lang="html">
 * <md-grid-list
 *     md-cols-sm="2"
 *     md-cols-md="4"
 *     md-cols-lg="8"

 * (ie. `md-colspan-sm="4"`)
 *
 * @param {number=} md-colspan The number of columns to span (default 1). Cannot
 *    exceed the number of columns in the grid. Supports interpolation.

/**
 * @ngdoc directive
 * @name mdInput
 * @restrict E
 * @module material.components.input
 *
 * @description
 * You can use any `<input>` or `<textarea>` element as a child of an `<md-input-container>`. This
 * allows you to build complex forms for data entry.
 *
 * When the input is required and uses a floating label, then the label will automatically contain
 * an asterisk (`*`).<br/>
 * This behavior can be disabled by using the `md-no-asterisk` attribute.
 *
 * @param {number=} md-maxlength The maximum number of characters allowed in this input. If this is
 *   specified, a character counter will be shown underneath the input.<br/><br/>
 *   The purpose of **`md-maxlength`** is exactly to show the max length counter text. If you don't
 *   want the counter text and only need "plain" validation, you can use the "simple" `ng-maxlength`
 *   or maxlength attributes.<br/><br/>
 *   **Note:** Only valid for text/string inputs (not numeric).
 *
 * @param {string=} aria-label Aria-label is required when no label is present.  A warning message
 *   will be logged in the console if not present.
 * @param {string=} placeholder An alternative approach to using aria-label when the label is not
 *   PRESENT. The placeholder text is copied to the aria-label attribute.
 * @param md-no-autogrow {boolean=} When present, textareas will not grow automatically.
 * @param md-no-asterisk {boolean=} When present, an asterisk will not be appended to the inputs floating label
 * @param md-no-resize {boolean=} Disables the textarea resize handle.
 * @param {number=} max-rows The maximum amount of rows for a textarea.
 * @param md-detect-hidden {boolean=} When present, textareas will be sized properly when they are
 *   revealed after being hidden. This is off by default for performance reasons because it
 *   guarantees a reflow every digest cycle.
 *

 * <hljs lang="html">

 *   <input type="text" ng-model="color" required md-maxlength="10">
 * </md-input-container>
 * </hljs>
 *
 * <h3>With Errors</h3>
 *
 * `md-input-container` also supports errors using the standard `ng-messages` directives and
 * animates the messages when they become visible using from the `ngEnter`/`ngLeave` events or
 * the `ngShow`/`ngHide` events.
 *
 * By default, the messages will be hidden until the input is in an error state. This is based off
 * of the `md-is-error` expression of the `md-input-container`. This gives the user a chance to
 * fill out the form before the errors become visible.
 *
 * <hljs lang="html">
 * <form name="colorForm">
 *   <md-input-container>
 *     <label>Favorite Color</label>
 *     <input name="favoriteColor" ng-model="favoriteColor" required>
 *     <div ng-messages="colorForm.favoriteColor.$error">
 *       <div ng-message="required">This is required!</div>
 *     </div>
 *   </md-input-container>
 * </form>
 * </hljs>
 *
 * We automatically disable this auto-hiding functionality if you provide any of the following
 * visibility directives on the `ng-messages` container:
 *
 *  - `ng-if`
 *  - `ng-show`/`ng-hide`
 *  - `ng-switch-when`/`ng-switch-default`
 *
 * You can also disable this functionality manually by adding the `md-auto-hide="false"` expression
 * to the `ng-messages` container. This may be helpful if you always want to see the error messages
 * or if you are building your own visibilty directive.
 *
 * _<b>Note:</b> The `md-auto-hide` attribute is a static string that is  only checked upon
 * initialization of the `ng-messages` directive to see if it equals the string `false`._

 *
 * <h3>Notes</h3>
 *
 * - Requires [ngMessages](https://docs.angularjs.org/api/ngMessages).
 * - Behaves like the [AngularJS input directive](https://docs.angularjs.org/api/ng/directive/input).
 *
 * The `md-input` and `md-input-container` directives use very specific positioning to achieve the
 * error animation effects. Therefore, it is *not* advised to use the Layout system inside of the
 * `<md-input-container>` tags. Instead, use relative or absolute positioning.
 *
 *
 * <h3>Textarea directive</h3>
 * The `textarea` element within a `md-input-container` has the following specific behavior:
 * - By default the `textarea` grows as the user types. This can be disabled via the `md-no-autogrow`
 * attribute.
 * - If a `textarea` has the `rows` attribute, it will treat the `rows` as the minimum height and will
 * continue growing as the user types. For example a textarea with `rows="3"` will be 3 lines of text
 * high initially. If no rows are specified, the directive defaults to 1.
 * - The textarea's height gets set on initialization, as well as while the user is typing. In certain situations
 * (e.g. while animating) the directive might have been initialized, before the element got it's final height. In
 * those cases, you can trigger a resize manually by broadcasting a `md-resize-textarea` event on the scope.
 * - If you want a `textarea` to stop growing at a certain point, you can specify the `max-rows` attribute.
 * - The textarea's bottom border acts as a handle which users can drag, in order to resize the element vertically.
 * Once the user has resized a `textarea`, the autogrowing functionality becomes disabled. If you don't want a
 * `textarea` to be resizeable by the user, you can add the `md-no-resize` attribute.

 * @description
 * A `md-list-item` element can be used to represent some information in a row.<br/>
 *
 * @usage
 * ### Single Row Item
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>Single Row Item</span>
 *   </md-list-item>
 * </hljs>
 *
 * ### Multiple Lines
 * By using the following markup, you will be able to have two lines inside of one `md-list-item`.
 *
 * <hljs lang="html">
 *   <md-list-item class="md-2-line">
 *     <div class="md-list-item-text" layout="column">
 *       <p>First Line</p>
 *       <p>Second Line</p>
 *     </div>
 *   </md-list-item>
 * </hljs>
 *
 * It is also possible to have three lines inside of one list item.
 *
 * <hljs lang="html">
 *   <md-list-item class="md-3-line">
 *     <div class="md-list-item-text" layout="column">
 *       <p>First Line</p>
 *       <p>Second Line</p>
 *       <p>Third Line</p>
 *     </div>
 *   </md-list-item>
 * </hljs>
 *
 * ### Secondary Items
 * Secondary items are elements which will be aligned at the end of the `md-list-item`.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>Single Row Item</span>
 *     <md-button class="md-secondary">
 *       Secondary Button
 *     </md-button>
 *   </md-list-item>
 * </hljs>
 *
 * It also possible to have multiple secondary items inside of one `md-list-item`.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>Single Row Item</span>
 *     <md-button class="md-secondary">First Button</md-button>
 *     <md-button class="md-secondary">Second Button</md-button>
 *   </md-list-item>
 * </hljs>
 *
 * ### Proxy Item
 * Proxies are elements, which will execute their specific action on click<br/>
 * Currently supported proxy items are
 * - `md-checkbox` (Toggle)
 * - `md-switch` (Toggle)
 * - `md-menu` (Open)
 *
 * This means, when using a supported proxy item inside of `md-list-item`, the list item will
 * automatically become clickable and executes the associated action of the proxy element on click.
 *
 * It is possible to disable this behavior by applying the `md-no-proxy` class to the list item.
 *
 * <hljs lang="html">
 *   <md-list-item class="md-no-proxy">
 *     <span>No Proxy List</span>
 *     <md-checkbox class="md-secondary"></md-checkbox>
 *   </md-list-item>
 * </hljs>
 *
 * Here are a few examples of proxy elements inside of a list item.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>First Line</span>
 *     <md-checkbox class="md-secondary"></md-checkbox>
 *   </md-list-item>
 * </hljs>
 *
 * The `md-checkbox` element will be automatically detected as a proxy element and will toggle on click.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <span>First Line</span>
 *     <md-switch class="md-secondary"></md-switch>
 *   </md-list-item>
 * </hljs>
 *
 * The recognized `md-switch` will toggle its state, when the user clicks on the `md-list-item`.
 *
 * It is also possible to have a `md-menu` inside of a `md-list-item`.
 * <hljs lang="html">
 *   <md-list-item>
 *     <p>Click anywhere to fire the secondary action</p>
 *     <md-menu class="md-secondary">
 *       <md-button class="md-icon-button">
 *         <md-icon md-svg-icon="communication:message"></md-icon>
 *       </md-button>
 *       <md-menu-content width="4">
 *         <md-menu-item>
 *           <md-button>
 *             Redial
 *           </md-button>
 *         </md-menu-item>
 *         <md-menu-item>
 *           <md-button>
 *             Check voicemail
 *           </md-button>
 *         </md-menu-item>
 *         <md-menu-divider></md-menu-divider>
 *         <md-menu-item>
 *           <md-button>
 *             Notifications
 *           </md-button>
 *         </md-menu-item>
 *       </md-menu-content>
 *     </md-menu>
 *   </md-list-item>
 * </hljs>
 *
 * The menu will automatically open, when the users clicks on the `md-list-item`.<br/>
 *
 * If the developer didn't specify any position mode on the menu, the `md-list-item` will automatically detect the
 * position mode and applies it to the `md-menu`.
 *
 * ### Avatars
 * Sometimes you may want to have some avatars inside of the `md-list-item `.<br/>
 * You are able to create a optimized icon for the list item, by applying the `.md-avatar` class on the `<img>` element.
 *
 * <hljs lang="html">
 *   <md-list-item>
 *     <img src="my-avatar.png" class="md-avatar">
 *     <span>Alan Turing</span>
 * </hljs>
 *
 * When using `<md-icon>` for an avatar, you have to use the `.md-avatar-icon` class.
 * <hljs lang="html">
 *   <md-list-item>
 *     <md-icon class="md-avatar-icon" md-svg-icon="avatars:timothy"></md-icon>
 *     <span>Timothy Kopra</span>
 *   </md-list-item>
 * </hljs>
 *
 * In cases, you have a `md-list-item`, which doesn't have any avatar,
 * but you want to align it with the other avatar items, you have to use the `.md-offset` class.
 *
 * <hljs lang="html">
 *   <md-list-item class="md-offset">
 *     <span>Jon Doe</span>
 *   </md-list-item>
 * </hljs>
 *
 * ### DOM modification
 * The `md-list-item` component automatically detects if the list item should be clickable.
 *
 * ---
 * If the `md-list-item` is clickable, we wrap all content inside of a `<div>` and create
 * an overlaying button, which will will execute the given actions (like `ng-href`, `ng-click`)
 *
 * We create an overlaying button, instead of wrapping all content inside of the button,
 * because otherwise some elements may not be clickable inside of the button.
 *
 * ---
 * When using a secondary item inside of your list item, the `md-list-item` component will automatically create
 * a secondary container at the end of the `md-list-item`, which contains all secondary items.
 *
 * The secondary item container is not static, because otherwise the overflow will not work properly on the
 * list item.

/**
 * @ngdoc method
 * @name $mdPanel#create
 * @description
 * Creates a panel with the specified options.
 *
 * @param config {!Object=} Specific configuration object that may contain the
 *     following properties:
 *
 *   - `id` - `{string=}`: An ID to track the panel by. When an ID is provided,
 *     the created panel is added to a tracked panels object. Any subsequent
 *     requests made to create a panel with that ID are ignored. This is useful
 *     in having the panel service not open multiple panels from the same user
 *     interaction when there is no backdrop and events are propagated. Defaults
 *     to an arbitrary string that is not tracked.
 *   - `template` - `{string=}`: HTML template to show in the panel. This
 *     **must** be trusted HTML with respect to AngularJS’s
 *     [$sce service](https://docs.angularjs.org/api/ng/service/$sce).
 *   - `templateUrl` - `{string=}`: The URL that will be used as the content of
 *     the panel.
 *   - `contentElement` - `{(string|!angular.JQLite|!Element)=}`: Pre-compiled
 *     element to be used as the panel's content.
 *   - `controller` - `{(function|string)=}`: The controller to associate with
 *     the panel. The controller can inject a reference to the returned
 *     panelRef, which allows the panel to be closed, hidden, and shown. Any
 *     fields passed in through locals or resolve will be bound to the
 *     controller.
 *   - `controllerAs` - `{string=}`: An alias to assign the controller to on
 *     the scope.
 *   - `bindToController` - `{boolean=}`: Binds locals to the controller
 *     instead of passing them in. Defaults to true, as this is a best
 *     practice.
 *   - `locals` - `{Object=}`: An object containing key/value pairs. The keys
 *     will be used as names of values to inject into the controller. For
 *     example, `locals: {three: 3}` would inject `three` into the controller,
 *     with the value 3. 'mdPanelRef' is a reserved key, and will always 
 *     be set to the created MdPanelRef instance.
 *   - `resolve` - `{Object=}`: Similar to locals, except it takes promises as
 *     values. The panel will not open until all of the promises resolve.
 *   - `attachTo` - `{(string|!angular.JQLite|!Element)=}`: The element to
 *     attach the panel to. Defaults to appending to the root element of the
 *     application.
 *   - `propagateContainerEvents` - `{boolean=}`: Whether pointer or touch
 *     events should be allowed to propagate 'go through' the container, aka the
 *     wrapper, of the panel. Defaults to false.
 *   - `panelClass` - `{string=}`: A css class to apply to the panel element.
 *     This class should define any borders, box-shadow, etc. for the panel.
 *   - `zIndex` - `{number=}`: The z-index to place the panel at.
 *     Defaults to 80.
 *   - `position` - `{MdPanelPosition=}`: An MdPanelPosition object that
 *     specifies the alignment of the panel. For more information, see
 *     `MdPanelPosition`.
 *   - `clickOutsideToClose` - `{boolean=}`: Whether the user can click
 *     outside the panel to close it. Defaults to false.
 *   - `escapeToClose` - `{boolean=}`: Whether the user can press escape to
 *     close the panel. Defaults to false.
 *   - `onCloseSuccess` - `{function(!panelRef, string)=}`: Function that is
 *     called after the close successfully finishes. The first parameter passed
 *     into this function is the current panelRef and the 2nd is an optional
 *     string explaining the close reason. The currently supported closeReasons
 *     can be found in the MdPanelRef.closeReasons enum. These are by default
 *     passed along by the panel.
 *   - `trapFocus` - `{boolean=}`: Whether focus should be trapped within the
 *     panel. If `trapFocus` is true, the user will not be able to interact
 *     with the rest of the page until the panel is dismissed. Defaults to
 *     false.
 *   - `focusOnOpen` - `{boolean=}`: An option to override focus behavior on
 *     open. Only disable if focusing some other way, as focus management is
 *     required for panels to be accessible. Defaults to true.
 *   - `fullscreen` - `{boolean=}`: Whether the panel should be full screen.
 *     Applies the class `._md-panel-fullscreen` to the panel on open. Defaults
 *     to false.
 *   - `animation` - `{MdPanelAnimation=}`: An MdPanelAnimation object that
 *     specifies the animation of the panel. For more information, see
 *     `MdPanelAnimation`.
 *   - `hasBackdrop` - `{boolean=}`: Whether there should be an opaque backdrop
 *     behind the panel. Defaults to false.
 *   - `disableParentScroll` - `{boolean=}`: Whether the user can scroll the
 *     page behind the panel. Defaults to false.
 *   - `onDomAdded` - `{function=}`: Callback function used to announce when
 *     the panel is added to the DOM.
 *   - `onOpenComplete` - `{function=}`: Callback function used to announce
 *     when the open() action is finished.
 *   - `onRemoving` - `{function=}`: Callback function used to announce the
 *     close/hide() action is starting.
 *   - `onDomRemoved` - `{function=}`: Callback function used to announce when
 *     the panel is removed from the DOM.
 *   - `origin` - `{(string|!angular.JQLite|!Element)=}`: The element to focus
 *     on when the panel closes. This is commonly the element which triggered
 *     the opening of the panel. If you do not use `origin`, you need to control
 *     the focus manually.
 *   - `groupName` - `{(string|!Array<string>)=}`: A group name or an array of
 *     group names. The group name is used for creating a group of panels. The
 *     group is used for configuring the number of open panels and identifying
 *     specific behaviors for groups. For instance, all tooltips could be
 *     identified using the same groupName.

 * the amount of visual change a user sees before they can view
 * and interact with content.
 *
 * Each operation should only be represented by one activity indicator
 * For example: one refresh operation should not display both a
 * refresh bar and an activity circle.
 *
 * For operations where the percentage of the operation completed
 * can be determined, use a determinate indicator. They give users
 * a quick sense of how long an operation will take.
 *
 * For operations where the user is asked to wait a moment while
 * something finishes up, and it’s not necessary to expose what's
 * happening behind the scenes and how long it will take, use an
 * indeterminate indicator.
 *
 * @param {string} md-mode Select from one of four modes: determinate, indeterminate, buffer or query.
 *
 * Note: if the `md-mode` value is set as undefined or specified as 1 of the four (4) valid modes, then `indeterminate`
 * will be auto-applied as the mode.
 *
 * Note: if not configured, the `md-mode="indeterminate"` will be auto injected as an attribute. If `value=""` is also specified, however,
 * then `md-mode="determinate"` would be auto-injected instead.
 * @param {number=} value In determinate and buffer modes, this number represents the percentage of the primary progress bar. Default: 0
 * @param {number=} md-buffer-value In the buffer mode, this number represents the percentage of the secondary progress bar. Default: 0
 * @param {boolean=} ng-disabled Determines whether to disable the progress element.

 *
 * When the select is required and uses a floating label, then the label will automatically contain
 * an asterisk (`*`). This behavior can be disabled by using the `md-no-asterisk` attribute.
 *
 * By default, the select will display with an underline to match other form elements. This can be
 * disabled by applying the `md-no-underline` CSS class.
 *
 * ### Option Params
 *
 * When applied, `md-option-empty` will mark the option as "empty" allowing the option to  clear the
 * select and put it back in it's default state. You may supply this attribute on any option you
 * wish, however, it is automatically applied to an option whose `value` or `ng-value` are not
 * defined.
 *
 * **Automatically Applied**
 *
 *  - `<md-option>`
 *  - `<md-option value>`
 *  - `<md-option value="">`
 *  - `<md-option ng-value>`
 *  - `<md-option ng-value="">`
 *
 * **NOT Automatically Applied**
 *
 *  - `<md-option ng-value="1">`
 *  - `<md-option ng-value="''">`
 *  - `<md-option ng-value="undefined">`
 *  - `<md-option value="undefined">` (this evaluates to the string `"undefined"`)
 *  - <code ng-non-bindable>&lt;md-option ng-value="{{someValueThatMightBeUndefined}}"&gt;</code>
 *
 * **Note:** A value of `undefined` ***is considered a valid value*** (and does not auto-apply this
 * attribute) since you may wish this to be your "Not Available" or "None" option.
 *
 * **Note:** Using the `value` attribute (as opposed to `ng-value`) always evaluates to a string, so
 * `value="null"` will require the test `ng-if="myValue != 'null'"` rather than `ng-if="!myValue"`.
 *
 * @param {expression} ng-model The model!
 * @param {boolean=} multiple When set to true, allows for more than one option to be selected. The model is an array with the selected choices.
 * @param {expression=} md-on-close Expression to be evaluated when the select is closed.
 * @param {expression=} md-on-open Expression to be evaluated when opening the select.
 * Will hide the select options and show a spinner until the evaluated promise resolves.
 * @param {expression=} md-selected-text Expression to be evaluated that will return a string
 * to be displayed as a placeholder in the select input box when it is closed. The value
 * will be treated as *text* (not html).
 * @param {expression=} md-selected-html Expression to be evaluated that will return a string
 * to be displayed as a placeholder in the select input box when it is closed. The value
 * will be treated as *html*. The value must either be explicitly marked as trustedHtml or
 * the ngSanitize module must be loaded.
 * @param {string=} placeholder Placeholder hint text.
 * @param md-no-asterisk {boolean=} When set to true, an asterisk will not be appended to the
 * floating label. **Note:** This attribute is only evaluated once; it is not watched.
 * @param {string=} aria-label Optional label for accessibility. Only necessary if no placeholder or
 * explicit label is present.
 * @param {string=} md-container-class Class list to get applied to the `.md-select-menu-container`
 * element (for custom styling).

 *
 * With a select-header
 *
 * When a developer needs to put more than just a text label in the
 * md-select-menu, they should use the md-select-header.
 * The user can put custom HTML inside of the header and style it to their liking.
 * One common use case of this would be a sticky search bar.
 *
 * When using the md-select-header the labels that would previously be added to the
 * OptGroupDirective are ignored.
 *
 * <hljs lang="html">
 *   <md-input-container>

 *
 * ## Selects and object equality
 * When using a `md-select` to pick from a list of objects, it is important to realize how javascript handles
 * equality. Consider the following example:
 * <hljs lang="js">
 * angular.controller('MyCtrl', function($scope) {
 *   $scope.users = [
 *     { id: 1, name: 'Bob' },
 *     { id: 2, name: 'Alice' },
 *     { id: 3, name: 'Steve' }
 *   ];
 *   $scope.selectedUser = { id: 1, name: 'Bob' };
 * });
 * </hljs>
 * <hljs lang="html">
 * <div ng-controller="MyCtrl">
 *   <md-select ng-model="selectedUser">
 *     <md-option ng-value="user" ng-repeat="user in users">{{ user.name }}</md-option>
 *   </md-select>
 * </div>
 * </hljs>
 *
 * At first one might expect that the select should be populated with "Bob" as the selected user. However,
 * this is not true. To determine whether something is selected,
 * `ngModelController` is looking at whether `$scope.selectedUser == (any user in $scope.users);`;
 *
 * Javascript's `==` operator does not check for deep equality (ie. that all properties
 * on the object are the same), but instead whether the objects are *the same object in memory*.
 * In this case, we have two instances of identical objects, but they exist in memory as unique
 * entities. Because of this, the select will have no value populated for a selected user.
 *
 * To get around this, `ngModelController` provides a `track by` option that allows us to specify a different
 * expression which will be used for the equality operator. As such, we can update our `html` to
 * make use of this by specifying the `ng-model-options="{trackBy: '$value.id'}"` on the `md-select`
 * element. This converts our equality expression to be
 * `$scope.selectedUser.id == (any id in $scope.users.map(function(u) { return u.id; }));`
 * which results in Bob being selected as desired.
 *
 * Working HTML:
 * <hljs lang="html">
 * <div ng-controller="MyCtrl">
 *   <md-select ng-model="selectedUser" ng-model-options="{trackBy: '$value.id'}">
 *     <md-option ng-value="user" ng-repeat="user in users">{{ user.name }}</md-option>
 *   </md-select>
 * </div>
 * </hljs>

 * @param {expression=} md-is-locked-open When this expression evaluates to true,

* The $mdMedia() service is exposed to the is-locked-open attribute, which
 * can be given a media query or one of the `sm`, `gt-sm`, `md`, `gt-md`, `lg` or `gt-lg` presets.

 *
 *   - `<md-sidenav md-is-locked-open="shouldLockOpen"></md-sidenav>`
 *   - `<md-sidenav md-is-locked-open="$mdMedia('min-width: 1000px')"></md-sidenav>`
 *   - `<md-sidenav md-is-locked-open="$mdMedia('sm')"></md-sidenav>` (locks open on small screens)

  * on the screen with an optional duration, and provides a simple promise API.
  *
  * The toast will be always positioned at the `bottom`, when the screen size is
  * between `600px` and `959px` (`sm` breakpoint)
  *
  * ## Restrictions on custom toasts
  * - The toast's template must have an outer `<md-toast>` element.
  * - For a toast action, use element with class `md-action`.
  * - Add the class `md-capsule` for curved corners.
  *
  * ### Custom Presets
  * Developers are also able to create their own preset, which can be easily used without repeating
  * their options each time.
  *
  * <hljs lang="js">
  *   $mdToastProvider.addPreset('testPreset', {
  *     options: function() {
  *       return {
  *         template:

  *         bindToController: true
  *       };
  *     }
  *   });
  * </hljs>
  *
  * After you created your preset at config phase, you can easily access it.
  *
  * <hljs lang="js">
  *   $mdToast.show(
  *     $mdToast.testPreset()
  *   );
  * </hljs>
  *
  * ## Parent container notes
  *
  * The toast is positioned using absolute positioning relative to its first non-static parent
  * container. Thus, if the requested parent container uses static positioning, we will temporarily
  * set its positioning to `relative` while the toast is visible and reset it when the toast is
  * hidden.
  *
  * Because of this, it is usually best to ensure that the parent container has a fixed height and
  * prevents scrolling by setting the `overflow: hidden;` style. Since the position is based off of
  * the parent's height, the toast may be mispositioned if you allow the parent to scroll.
  *
  * You can, however, have a scrollable element inside of the container; just make sure the
  * container itself does not scroll.

  *
  * @param {object} optionsOrPreset Either provide an `$mdToastPreset` returned from `simple()`
  * and `build()`, or an options object with the following properties:
  *
  *   - `templateUrl` - `{string=}`: The url of an html template file that will
  *     be used as the content of the toast. Restrictions: the template must
  *     have an outer `md-toast` element.
  *   - `template` - `{string=}`: Same as templateUrl, except this is an actual
  *     template string.
  *   - `autoWrap` - `{boolean=}`: Whether or not to automatically wrap the template content with a
  *     `<div class="md-toast-content">` if one is not provided. Defaults to true. Can be disabled if you provide a
  *     custom toast directive.
  *   - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified, it will create a new child scope.
  *     This scope will be destroyed when the toast is removed unless `preserveScope` is set to true.
  *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
  *   - `hideDelay` - `{number=}`: How many milliseconds the toast should stay
  *     active before automatically closing.  Set to 0 or false to have the toast stay open until
  *     closed manually. Default: 3000.
  *   - `position` - `{string=}`: Sets the position of the toast. <br/>
  *     Available: any combination of `'bottom'`, `'left'`, `'top'`, `'right'`, `'end'` and `'start'`.
  *     The properties `'end'` and `'start'` are dynamic and can be used for RTL support.<br/>
  *     Default combination: `'bottom left'`.
  *   - `toastClass` - `{string=}`: A class to set on the toast element.
  *   - `controller` - `{string=}`: The controller to associate with this toast.
  *     The controller will be injected the local `$mdToast.hide( )`, which is a function
  *     used to hide the toast.
  *   - `locals` - `{string=}`: An object containing key/value pairs. The keys will
  *     be used as names of values to inject into the controller. For example,
  *     `locals: {three: 3}` would inject `three` into the controller with the value
  *     of 3.
  *   - `bindToController` - `bool`: bind the locals to the controller, instead of passing them in.
  *   - `resolve` - `{object=}`: Similar to locals, except it takes promises as values
  *     and the toast will not open until the promises resolve.
  *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
  *   - `parent` - `{element=}`: The element to append the toast to. Defaults to appending
  *     to the root element of the application.
  *
  * @returns {promise} A promise that can be resolved with `$mdToast.hide()` or
  * rejected with `$mdToast.cancel()`. `$mdToast.hide()` will resolve either with a Boolean
  * value == 'true' or the value passed as an argument to `$mdToast.hide()`.

 * @description
 * `md-toolbar` is used to place a toolbar in your app.
 *
 * Toolbars are usually used above a content area to display the title of the
 * current page, and show relevant action buttons for that page.
 *
 * You can change the height of the toolbar by adding either the
 * `md-medium-tall` or `md-tall` class to the toolbar.
 *
 * @usage
 * <hljs lang="html">
 * <div layout="column" layout-fill>
 *   <md-toolbar>
 *
 *     <div class="md-toolbar-tools">
 *       <h2 md-truncate flex>My App's Title</h2>
 *
 *       <md-button>
 *         Right Bar Button
 *       </md-button>
 *     </div>
 *
 *   </md-toolbar>
 *   <md-content>
 *     Hello!
 *   </md-content>
 * </div>
 * </hljs>
 *
 * <i><b>Note:</b> The code above shows usage with the `md-truncate` component which provides an
 * ellipsis if the title is longer than the width of the Toolbar.</i>
 *
 * ## CSS & Styles
 *
 * The `<md-toolbar>` provides a few custom CSS classes that you may use to enhance the
 * functionality of your toolbar.
 *
 * <div>
 * <docs-css-api-table>
 *
 *   <docs-css-selector code="md-toolbar .md-toolbar-tools">
 *     The `md-toolbar-tools` class provides quite a bit of automatic styling for your toolbar
 *     buttons and text. When applied, it will center the buttons and text vertically for you.
 *   </docs-css-selector>
 *
 * </docs-css-api-table>
 * </div>
 *
 * ### Private Classes
 *
 * Currently, the only private class is the `md-toolbar-transitions` class. All other classes are
 * considered public.
 *
 * @param {boolean=} md-scroll-shrink Whether the header should shrink away as
 * the user scrolls down, and reveal itself as the user scrolls up.
 *
 * _**Note (1):** for scrollShrink to work, the toolbar must be a sibling of a
 * `md-content` element, placed before it. See the scroll shrink demo._
 *
 * _**Note (2):** The `md-scroll-shrink` attribute is only parsed on component
 * initialization, it does not watch for scope changes._
 *
 *
 * @param {number=} md-shrink-speed-factor How much to change the speed of the toolbar's
 * shrinking by. For example, if 0.25 is given then the toolbar will shrink
 * at one fourth the rate at which the user scrolls down. Default 0.5.

 * @ngdoc directive
 * @name mdTooltip
 * @module material.components.tooltip
 * @description
 * Tooltips are used to describe elements that are interactive and primarily
 * graphical (not textual).
 *
 * Place a `<md-tooltip>` as a child of the element it describes.
 *
 * A tooltip will activate when the user hovers over, focuses, or touches the
 * parent element.
 *
 * @usage
 * <hljs lang="html">
 *   <md-button class="md-fab md-accent" aria-label="Play">
 *     <md-tooltip>Play Music</md-tooltip>
 *     <md-icon md-svg-src="img/icons/ic_play_arrow_24px.svg"></md-icon>
 *   </md-button>
 * </hljs>
 *
 * @param {number=} md-z-index The visual level that the tooltip will appear
 *     in comparison with the rest of the elements of the application.
 * @param {expression=} md-visible Boolean bound to whether the tooltip is
 *     currently visible.
 * @param {number=} md-delay How many milliseconds to wait to show the tooltip
 *     after the user hovers over, focuses, or touches the parent element.
 *     Defaults to 0ms on non-touch devices and 75ms on touch.
 * @param {boolean=} md-autohide If present or provided with a boolean value,
 *     the tooltip will hide on mouse leave, regardless of focus.
 * @param {string=} md-direction The direction that the tooltip is shown,
 *     relative to the parent element. Supports top, right, bottom, and left.
 *     Defaults to bottom.

 * @ngdoc directive
 * @name mdVirtualRepeatContainer
 * @module material.components.virtualRepeat
 * @restrict E
 * @description
 * `md-virtual-repeat-container` provides the scroll container for md-virtual-repeat.
 *
 * VirtualRepeat is a limited substitute for ng-repeat that renders only
 * enough DOM nodes to fill the container and recycling them as the user scrolls.
 *
 * Once an element is not visible anymore, the VirtualRepeat recycles it and will reuse it for
 * another visible item by replacing the previous dataset with the new one.
 *
 * ### Common Issues
 *
 * - When having one-time bindings inside of the view template, the VirtualRepeat will not properly
 *   update the bindings for new items, since the view will be recycled.
 *
 * - Directives inside of a VirtualRepeat will be only compiled (linked) once, because those
 *   are will be recycled items and used for other items.
 *   The VirtualRepeat just updates the scope bindings.
 *
 *
 * ### Notes

 * [RecyclerView](https://developer.android.com/reference/android/support/v7/widget/RecyclerView.html)

/**
 * @ngdoc directive
 * @name mdVirtualRepeat
 * @module material.components.virtualRepeat
 * @restrict A
 * @priority 1000
 * @description
 * `md-virtual-repeat` specifies an element to repeat using virtual scrolling.
 *
 * Virtual repeat is a limited substitute for ng-repeat that renders only
 * enough DOM nodes to fill the container and recycling them as the user scrolls.
 *
 * Arrays, but not objects are supported for iteration.
 * Track by, as alias, and (key, value) syntax are not supported.
 *
 * ### On-Demand Async Item Loading
 *
 * When using the `md-on-demand` attribute and loading some asynchronous data, the `getItemAtIndex` function will
 * mostly return nothing.
 *
 * <hljs lang="js">
 *   DynamicItems.prototype.getItemAtIndex = function(index) {
 *     if (this.pages[index]) {
 *       return this.pages[index];
 *     } else {
 *       // This is an asynchronous action and does not return any value.
 *       this.loadPage(index);
 *     }
 *   };
 * </hljs>
 *
 * This means that the VirtualRepeat will not have any value for the given index.<br/>
 * After the data loading completed, the user expects the VirtualRepeat to recognize the change.
 *
 * To make sure that the VirtualRepeat properly detects any change, you need to run the operation
 * in another digest.
 *
 * <hljs lang="js">
 *   DynamicItems.prototype.loadPage = function(index) {
 *     var self = this;
 *
 *     // Trigger a new digest by using $timeout
 *     $timeout(function() {
 *       self.pages[index] = Data;
 *     });
 *   };
 * </hljs>
 *
 * > <b>Note:</b> Please also review the
 *   <a ng-href="api/directive/mdVirtualRepeatContainer">VirtualRepeatContainer</a> documentation
 *   for more information.
 *
 * @usage
 * <hljs lang="html">
 * <md-virtual-repeat-container>
 *   <div md-virtual-repeat="i in items">Hello {{i}}!</div>
 * </md-virtual-repeat-container>
 *
 * <md-virtual-repeat-container md-orient-horizontal>
 *   <div md-virtual-repeat="i in items" md-item-size="20">Hello {{i}}!</div>
 * </md-virtual-repeat-container>
 * </hljs>
 *
 * @param {number=} md-item-size The height or width of the repeated elements (which must be
 *   identical for each element). Optional. Will attempt to read the size from the dom if missing,
 *   but still assumes that all repeated nodes have same height or width.
 * @param {string=} md-extra-name Evaluates to an additional name to which the current iterated item
 *   can be assigned on the repeated scope (needed for use in `md-autocomplete`).
 * @param {boolean=} md-on-demand When present, treats the md-virtual-repeat argument as an object
 *   that can fetch rows rather than an array.
 *
 *   **NOTE:** This object must implement the following interface with two (2) methods:
 *
 *   - `getItemAtIndex: function(index) [object]` The item at that index or null if it is not yet
 *     loaded (it should start downloading the item in that case).
 *   - `getLength: function() [number]` The data length to which the repeater container
 *     should be sized. Ideally, when the count is known, this method should return it.
 *     Otherwise, return a higher number than the currently loaded items to produce an
 *     infinite-scroll behavior.

/**
 * @ngdoc directive
 * @name mdAutocomplete
 * @module material.components.autocomplete
 *
 * @description
 * `<md-autocomplete>` is a special input component with a drop-down of all possible matches to a
 *     custom query. This component allows you to provide real-time suggestions as the user types
 *     in the input area.
 *
 * To start, you will need to specify the required parameters and provide a template for your
 *     results. The content inside `md-autocomplete` will be treated as a template.
 *
 * In more complex cases, you may want to include other content such as a message to display when
 *     no matches were found.  You can do this by wrapping your template in `md-item-template` and
 *     adding a tag for `md-not-found`.  An example of this is shown below.
 *
 * To reset the displayed value you must clear both values for `md-search-text` and `md-selected-item`.
 *
 * ### Validation
 *
 * You can use `ng-messages` to include validation the same way that you would normally validate;
 *     however, if you want to replicate a standard input with a floating label, you will have to
 *     do the following:
 *
 * - Make sure that your template is wrapped in `md-item-template`
 * - Add your `ng-messages` code inside of `md-autocomplete`
 * - Add your validation properties to `md-autocomplete` (ie. `required`)
 * - Add a `name` to `md-autocomplete` (to be used on the generated `input`)
 *
 * There is an example below of how this should look.
 *
 * ### Snapping Drop-Down
 *
 * You can cause the autocomplete drop-down to snap to an ancestor element by applying the
 *     `md-autocomplete-snap` attribute to that element. You can also snap to the width of
 *     the `md-autocomplete-snap` element by setting the attribute's value to `width`
 *     (ie. `md-autocomplete-snap="width"`).
 *
 * ### Notes
 *
 * **Autocomplete Dropdown Items Rendering**
 *
 * The `md-autocomplete` uses the the <a ng-href="api/directive/mdVirtualRepeatContainer">VirtualRepeat</a>
 * directive for displaying the results inside of the dropdown.<br/>
 *
 * > When encountering issues regarding the item template please take a look at the
 *   <a ng-href="api/directive/mdVirtualRepeatContainer">VirtualRepeatContainer</a> documentation.
 *
 * **Autocomplete inside of a Virtual Repeat**
 *
 * When using the `md-autocomplete` directive inside of a
 * <a ng-href="api/directive/mdVirtualRepeatContainer">VirtualRepeatContainer</a> the dropdown items might
 * not update properly, because caching of the results is enabled by default.
 *
 * The autocomplete will then show invalid dropdown items, because the VirtualRepeat only updates the
 * scope bindings, rather than re-creating the `md-autocomplete` and the previous cached results will be used.
 *
 * > To avoid such problems ensure that the autocomplete does not cache any results.

 *     When the dropdown doesn't fit into the viewport, the dropdown will shrink
 *     as less as possible.
 * @param {string=} md-dropdown-position Overrides the default dropdown position. Options: `top`, `bottom`.
 * @param {string=} ng-trim If set to false, the search text will be not trimmed automatically.
 *     Defaults to true.
 * @param {string=} ng-pattern Adds the pattern validator to the ngModel of the search text.
 *     [ngPattern Directive](https://docs.angularjs.org/api/ng/directive/ngPattern)
 *
 * @usage
 * ### Basic Example
 * <hljs lang="html">
 *   <md-autocomplete
 *       md-selected-item="selectedItem"
 *       md-search-text="searchText"
 *       md-items="item in getMatches(searchText)"
 *       md-item-text="item.display">
 *     <span md-highlight-text="searchText">{{item.display}}</span>
 *   </md-autocomplete>
 * </hljs>
 *
 * ### Example with "not found" message
 * <hljs lang="html">
 * <md-autocomplete
 *     md-selected-item="selectedItem"
 *     md-search-text="searchText"
 *     md-items="item in getMatches(searchText)"
 *     md-item-text="item.display">
 *   <md-item-template>
 *     <span md-highlight-text="searchText">{{item.display}}</span>
 *   </md-item-template>
 *   <md-not-found>
 *     No matches found.
 *   </md-not-found>
 * </md-autocomplete>
 * </hljs>
 *
 * In this example, our code utilizes `md-item-template` and `md-not-found` to specify the
 *     different parts that make up our component.
 *
 * ### Clear button for the input
 * By default, for floating label autocomplete's the clear button is not showing up
 * ([See specs](https://material.google.com/components/text-fields.html#text-fields-auto-complete-text-field))
 *
 * Nevertheless, developers are able to explicitly toggle the clear button for all types of autocomplete's.
 *
 * <hljs lang="html">
 *   <md-autocomplete ... md-clear-button="true"></md-autocomplete>
 *   <md-autocomplete ... md-clear-button="false"></md-autocomplete>
 * </hljs>
 *
 * ### Example with validation
 * <hljs lang="html">
 * <form name="autocompleteForm">
 *   <md-autocomplete
 *       required
 *       md-input-name="autocomplete"
 *       md-selected-item="selectedItem"
 *       md-search-text="searchText"
 *       md-items="item in getMatches(searchText)"
 *       md-item-text="item.display">
 *     <md-item-template>
 *       <span md-highlight-text="searchText">{{item.display}}</span>
 *     </md-item-template>
 *     <div ng-messages="autocompleteForm.autocomplete.$error">
 *       <div ng-message="required">This field is required</div>
 *     </div>
 *   </md-autocomplete>
 * </form>
 * </hljs>
 *
 * In this example, our code utilizes `md-item-template` and `ng-messages` to specify
 *     input validation for the field.
 *
 * ### Asynchronous Results
 * The autocomplete items expression also supports promises, which will resolve with the query results.
 *
 * <hljs lang="js">
 *   function AppController($scope, $http) {
 *     $scope.query = function(searchText) {
 *       return $http
 *         .get(BACKEND_URL + '/items/' + searchText)
 *         .then(function(data) {
 *           // Map the response object to the data object.
 *           return data;
 *         });
 *     };
 *   }
 * </hljs>
 *
 * <hljs lang="html">
 *   <md-autocomplete
 *       md-selected-item="selectedItem"
 *       md-search-text="searchText"
 *       md-items="item in query(searchText)">
 *     <md-item-template>
 *       <span md-highlight-text="searchText">{{item}}</span>
 *     </md-item-template>
 * </md-autocomplete>
 * </hljs>

  /**
   * @ngdoc directive
   * @name mdChips
   * @module material.components.chips
   *
   * @description
   * `<md-chips>` is an input component for building lists of strings or objects. The list items are
   * displayed as 'chips'. This component can make use of an `<input>` element or an 
   * `<md-autocomplete>` element.
   *
   * ### Custom templates
   * A custom template may be provided to render the content of each chip. This is achieved by
   * specifying an `<md-chip-template>` element containing the custom content as a child of
   * `<md-chips>`.
   *
   * Note: Any attributes on
   * `<md-chip-template>` will be dropped as only the innerHTML is used for the chip template. The
   * variables `$chip` and `$index` are available in the scope of `<md-chip-template>`, representing
   * the chip object and its index in the list of chips, respectively.
   * To override the chip delete control, include an element (ideally a button) with the attribute
   * `md-chip-remove`. A click listener to remove the chip will be added automatically. The element
   * is also placed as a sibling to the chip content (on which there are also click listeners) to
   * avoid a nested ng-click situation.
   *
   * <!-- Note: We no longer want to include this in the site docs; but it should remain here for
   * future developers and those looking at the documentation.
   *
   * <h3> Pending Features </h3>
   * <ul style="padding-left:20px;">

   * </ul>
   *
   * //-->
   *
   * Sometimes developers want to limit the amount of possible chips.<br/>
   * You can specify the maximum amount of chips by using the following markup.
   *
   * <hljs lang="html">
   *   <md-chips
   *       ng-model="myItems"
   *       placeholder="Add an item"
   *       md-max-chips="5">
   *   </md-chips>
   * </hljs>
   *
   * In some cases, you have an autocomplete inside of the `md-chips`.<br/>
   * When the maximum amount of chips has been reached, you can also disable the autocomplete selection.<br/>
   * Here is an example markup.
   *
   * <hljs lang="html">
   *   <md-chips ng-model="myItems" md-max-chips="5">
   *     <md-autocomplete ng-hide="myItems.length > 5" ...></md-autocomplete>
   *   </md-chips>
   * </hljs>
   *
   * ### Accessibility
   *
   * The `md-chips` component supports keyboard and screen reader users since Version 1.1.2. In
   * order to achieve this, we modified the chips behavior to select newly appended chips for
   * `300ms` before re-focusing the input and allowing the user to type.
   *
   * For most users, this delay is small enough that it will not be noticeable but allows certain
   * screen readers to function properly (JAWS and NVDA in particular).
   *
   * We introduced a new `md-chip-append-delay` option to allow developers to better control this
   * behavior.
   *
   * Please refer to the documentation of this option (below) for more information.
   *
   * @param {string=|object=} ng-model A model to which the list of items will be bound.
   * @param {string=} placeholder Placeholder text that will be forwarded to the input.
   * @param {string=} secondary-placeholder Placeholder text that will be forwarded to the input,
   *    displayed when there is at least one item in the list
   * @param {boolean=} md-removable Enables or disables the deletion of chips through the
   *    removal icon or the Delete/Backspace key. Defaults to true.
   * @param {boolean=} readonly Disables list manipulation (deleting or adding list items), hiding
   *    the input and delete buttons. If no `ng-model` is provided, the chips will automatically be
   *    marked as readonly.<br/><br/>
   *    When `md-removable` is not defined, the `md-remove` behavior will be overwritten and disabled.
   * @param {string=} md-enable-chip-edit Set this to "true" to enable editing of chip contents. The user can 
   *    go into edit mode with pressing "space", "enter", or double clicking on the chip. Chip edit is only
   *    supported for chips with basic template.
   * @param {number=} md-max-chips The maximum number of chips allowed to add through user input.
   *    <br/><br/>The validation property `md-max-chips` can be used when the max chips
   *    amount is reached.
   * @param {boolean=} md-add-on-blur When set to true, remaining text inside of the input will
   *    be converted into a new chip on blur.
   * @param {expression} md-transform-chip An expression of form `myFunction($chip)` that when called
   *    expects one of the following return values:
   *    - an object representing the `$chip` input string
   *    - `undefined` to simply add the `$chip` input string, or
   *    - `null` to prevent the chip from being appended
   * @param {expression=} md-on-add An expression which will be called when a chip has been
   *    added.
   * @param {expression=} md-on-remove An expression which will be called when a chip has been
   *    removed.
   * @param {expression=} md-on-select An expression which will be called when a chip is selected.
   * @param {boolean} md-require-match If true, and the chips template contains an autocomplete,
   *    only allow selection of pre-defined chips (i.e. you cannot add new ones).
   * @param {string=} input-aria-label A string read by screen readers to identify the input.
   * @param {string=} container-hint A string read by screen readers informing users of how to
   *    navigate the chips. Used in readonly mode.
   * @param {string=} delete-hint A string read by screen readers instructing users that pressing
   *    the delete key will remove the chip.
   * @param {string=} delete-button-label A label for the delete button. Also hidden and read by
   *    screen readers.
   * @param {expression=} md-separator-keys An array of key codes used to separate chips.
   * @param {string=} md-chip-append-delay The number of milliseconds that the component will select
   *    a newly appended chip before allowing a user to type into the input. This is **necessary**
   *    for keyboard accessibility for screen readers. It defaults to 300ms and any number less than
   *    300 can cause issues with screen readers (particularly JAWS and sometimes NVDA).
   *
   *    _Available since Version 1.1.2._
   *
   *    **Note:** You can safely set this to `0` in one of the following two instances:
   *
   *    1. You are targeting an iOS or Safari-only application (where users would use VoiceOver) or
   *    only ChromeVox users.
   *
   *    2. If you have utilized the `md-separator-keys` to disable the `enter` keystroke in
   *    favor of another one (such as `,` or `;`).

  /**
   * @ngdoc directive
   * @name mdDatepicker
   * @module material.components.datepicker
   *
   * @param {Date} ng-model The component's model. Expects either a JavaScript Date object or a value that can be parsed into one (e.g. a ISO 8601 string).
   * @param {Object=} ng-model-options Allows tuning of the way in which `ng-model` is being updated. Also allows
   * for a timezone to be specified. <a href="https://docs.angularjs.org/api/ng/directive/ngModelOptions#usage">Read more at the ngModelOptions docs.</a>
   * @param {expression=} ng-change Expression evaluated when the model value changes.
   * @param {expression=} ng-focus Expression evaluated when the input is focused or the calendar is opened.
   * @param {expression=} ng-blur Expression evaluated when focus is removed from the input or the calendar is closed.
   * @param {boolean=} ng-disabled Whether the datepicker is disabled.
   * @param {boolean=} ng-required Whether a value is required for the datepicker.
   * @param {Date=} md-min-date Expression representing a min date (inclusive).
   * @param {Date=} md-max-date Expression representing a max date (inclusive).
   * @param {(function(Date): boolean)=} md-date-filter Function expecting a date and returning a boolean whether it can be selected or not.
   * @param {String=} md-placeholder The date input placeholder value.
   * @param {String=} md-open-on-focus When present, the calendar will be opened when the input is focused.
   * @param {Boolean=} md-is-open Expression that can be used to open the datepicker's calendar on-demand.
   * @param {String=} md-current-view Default open view of the calendar pane. Can be either "month" or "year".
   * @param {String=} md-hide-icons Determines which datepicker icons should be hidden. Note that this may cause the
   * datepicker to not align properly with other components. **Use at your own risk.** Possible values are:
   * * `"all"` - Hides all icons.
   * * `"calendar"` - Only hides the calendar icon.
   * * `"triangle"` - Only hides the triangle icon.
   * @param {Object=} md-date-locale Allows for the values from the `$mdDateLocaleProvider` to be
   * ovewritten on a per-element basis (e.g. `msgOpenCalendar` can be overwritten with
   * `md-date-locale="{ msgOpenCalendar: 'Open a special calendar' }"`).
   *
   * @description
   * `<md-datepicker>` is a component used to select a single date.
   * For information on how to configure internationalization for the date picker,
   * see `$mdDateLocaleProvider`.
   *
   * This component supports [ngMessages](https://docs.angularjs.org/api/ngMessages/directive/ngMessages).
   * Supported attributes are:
   * * `required`: whether a required date is not set.
   * * `mindate`: whether the selected date is before the minimum allowed date.
   * * `maxdate`: whether the selected date is after the maximum allowed date.
   * * `debounceInterval`: ms to delay input processing (since last debounce reset); default value 500ms
   *
   * @usage
   * <hljs lang="html">
   *   <md-datepicker ng-model="birthday"></md-datepicker>
   * </hljs>

/**
 * @ngdoc directive
 * @name mdIcon
 * @module material.components.icon
 *
 * @restrict E
 *
 * @description
 * The `md-icon` directive makes it easier to use vector-based icons in your app (as opposed to
 * raster-based icons types like PNG). The directive supports both icon fonts and SVG icons.
 *
 * Icons should be considered view-only elements that should not be used directly as buttons; instead nest a `<md-icon>`
 * inside a `md-button` to add hover and click features.
 *
 * ### Icon fonts
 * Icon fonts are a technique in which you use a font where the glyphs in the font are
 * your icons instead of text. Benefits include a straightforward way to bundle everything into a
 * single HTTP request, simple scaling, easy color changing, and more.
 *
 * `md-icon` lets you consume an icon font by letting you reference specific icons in that font
 * by name rather than character code.
 *
 * ### SVG
 * For SVGs, the problem with using `<img>` or a CSS `background-image` is that you can't take
 * advantage of some SVG features, such as styling specific parts of the icon with CSS or SVG
 * animation.
 *
 * `md-icon` makes it easier to use SVG icons by *inlining* the SVG into an `<svg>` element in the
 * document. The most straightforward way of referencing an SVG icon is via URL, just like a
 * traditional `<img>`. `$mdIconProvider`, as a convenience, lets you _name_ an icon so you can
 * reference it by name instead of URL throughout your templates.
 *
 * Additionally, you may not want to make separate HTTP requests for every icon, so you can bundle
 * your SVG icons together and pre-load them with $mdIconProvider as an icon set. An icon set can
 * also be given a name, which acts as a namespace for individual icons, so you can reference them
 * like `"social:cake"`.
 *
 * When using SVGs, both external SVGs (via URLs) or sets of SVGs [from icon sets] can be
 * easily loaded and used. When using font-icons, developers must follow three (3) simple steps:
 *
 * <ol>
 * <li>Load the font library. e.g.<br/>
 *    `<link href="https://fonts.googleapis.com/icon?family=Material+Icons"
 *    rel="stylesheet">`
 * </li>
 * <li>
 *   Use either (a) font-icon class names or (b) a fontset and a font ligature to render the font glyph by
 *   using its textual name _or_ numerical character reference. Note that `material-icons` is the default fontset when
 *   none is specified.
 * </li>
 * <li> Use any of the following templates: <br/>
 *   <ul>
 *     <li>`<md-icon md-font-icon="classname"></md-icon>`</li>
 *     <li>`<md-icon md-font-set="font library classname or alias">textual_name</md-icon>`</li>
 *     <li>`<md-icon> numerical_character_reference </md-icon>`</li>
 *     <li>`<md-icon ng_bind="'textual_name'"></md-icon>`</li>
 *     <li>`<md-icon ng-bind="scopeVariable"></md-icon>`</li>
 *   </ul>
 * </li>
 * </ol>
 *
 * Full details for these steps can be found:
 *
 * <ul>
 * <li>http://google.github.io/material-design-icons/</li>
 * <li>http://google.github.io/material-design-icons/#icon-font-for-the-web</li>
 * </ul>
 *
 * The Material Design icon style <code>.material-icons</code> and the icon font references are published in
 * Material Design Icons:
 *
 * <ul>
 * <li>https://design.google.com/icons/</li>
 * <li>https://design.google.com/icons/#ic_accessibility</li>
 * </ul>
 *
 * ### Localization
 *
 * Because an `md-icon` element's text content is not intended to translated, it is recommended to declare the text
 * content for an `md-icon` element in its start tag. Instead of using the HTML text content, consider using `ng-bind`
 * with a scope variable or literal string.
 *
 * Examples:
 *
 * <ul>
 *   <li>`<md-icon ng-bind="myIconVariable"></md-icon>`</li>
 *   <li>`<md-icon ng-bind="'menu'"></md-icon>`
 * </ul>

 * To use icon sets, developers are required to pre-register the sets using the `$mdIconProvider` service.
 * @param {string=} aria-label Labels icon for accessibility. If an empty string is provided, icon
 * will be hidden from accessibility layer with `aria-hidden="true"`. If there's no aria-label on the icon

/**
 * @ngdoc service
 * @name $mdIconProvider
 * @module material.components.icon
 *
 * @description
 * `$mdIconProvider` is used only to register icon IDs with URLs. These configuration features allow
 * icons and icon sets to be pre-registered and associated with source URLs **before** the `<md-icon />`
 * directives are compiled.
 *
 * If using font-icons, the developer is responsible for loading the fonts.
 *
 * If using SVGs, loading of the actual svg files are deferred to on-demand requests and are loaded
 * internally by the `$mdIcon` service using the `$templateRequest` service. When an SVG is
 * requested by name/ID, the `$mdIcon` service searches its registry for the associated source URL;
 * that URL is used to on-demand load and parse the SVG dynamically.
 *
 * The `$templateRequest` service expects the icons source to be loaded over trusted URLs.<br/>
 * This means, when loading icons from an external URL, you have to trust the URL in the `$sceDelegateProvider`.
 *
 * <hljs lang="js">
 *   app.config(function($sceDelegateProvider) {
 *     $sceDelegateProvider.resourceUrlWhitelist([
 *       // Adding 'self' to the whitelist, will allow requests from the current origin.
 *       'self',
 *       // Using double asterisks here, will allow all URLs to load.
 *       // We recommend to only specify the given domain you want to allow.
 *       '**'
 *     ]);
 *   });
 * </hljs>
 *
 * Read more about the [$sceDelegateProvider](https://docs.angularjs.org/api/ng/provider/$sceDelegateProvider).
 *
 * **Notice:** Most font-icons libraries do not support ligatures (for example `fontawesome`).<br/>
 *  In such cases you are not able to use the icon's ligature name - Like so:
 *
 *  <hljs lang="html">
 *    <md-icon md-font-set="fa">fa-bell</md-icon>
 *  </hljs>
 *
 * You should instead use the given unicode, instead of the ligature name.
 *
 * <p ng-hide="true"> ##// Notice we can't use a hljs element here, because the characters will be escaped.</p>
 *  ```html
 *    <md-icon md-font-set="fa">&#xf0f3</md-icon>
 *  ```
 *
 * All unicode ligatures are prefixed with the `&#x` string.
 *
 * @usage

    *
    *     // Configure URLs for icons specified by [set:]id.

/**
 * @ngdoc directive
 * @name mdMenu
 * @module material.components.menu
 * @restrict E
 * @description
 *
 * Menus are elements that open when clicked. They are useful for displaying
 * additional options within the context of an action.
 *
 * Every `md-menu` must specify exactly two child elements. The first element is what is
 * left in the DOM and is used to open the menu. This element is called the trigger element.
 * The trigger element's scope has access to `$mdMenu.open($event)`
 * which it may call to open the menu. By passing $event as argument, the
 * corresponding event is stopped from propagating up the DOM-tree. Similarly, `$mdMenu.close()`
 * can be used to close the menu.
 *
 * The second element is the `md-menu-content` element which represents the
 * contents of the menu when it is open. Typically this will contain `md-menu-item`s,
 * but you can do custom content as well.
 *
 * <hljs lang="html">
 * <md-menu>
 *  <!-- Trigger element is a md-button with an icon -->
 *  <md-button ng-click="$mdMenu.open($event)" class="md-icon-button" aria-label="Open sample menu">
 *    <md-icon md-svg-icon="call:phone"></md-icon>
 *  </md-button>
 *  <md-menu-content>
 *    <md-menu-item><md-button ng-click="doSomething()">Do Something</md-button></md-menu-item>
 *  </md-menu-content>
 * </md-menu>
 * </hljs>

 * ## Sizing Menus
 *
 * The width of the menu when it is open may be specified by specifying a `width`
 * attribute on the `md-menu-content` element.
 * See the [Material Design Spec](https://material.google.com/components/menus.html#menus-simple-menus)
 * for more information.
 *
 *
 * ## Aligning Menus
 *
 * When a menu opens, it is important that the content aligns with the trigger element.
 * Failure to align menus can result in jarring experiences for users as content
 * suddenly shifts. To help with this, `md-menu` provides serveral APIs to help
 * with alignment.
 *
 * ### Target Mode
 *
 * By default, `md-menu` will attempt to align the `md-menu-content` by aligning
 * designated child elements in both the trigger and the menu content.
 *
 * To specify the alignment element in the `trigger` you can use the `md-menu-origin`
 * attribute on a child element. If no `md-menu-origin` is specified, the `md-menu`
 * will be used as the origin element.
 *
 * Similarly, the `md-menu-content` may specify a `md-menu-align-target` for a
 * `md-menu-item` to specify the node that it should try and align with.
 *
 * In this example code, we specify an icon to be our origin element, and an
 * icon in our menu content to be our alignment target. This ensures that both
 * icons are aligned when the menu opens.
 *
 * <hljs lang="html">
 * <md-menu>
 *  <md-button ng-click="$mdMenu.open($event)" class="md-icon-button" aria-label="Open some menu">
 *    <md-icon md-menu-origin md-svg-icon="call:phone"></md-icon>
 *  </md-button>
 *  <md-menu-content>
 *    <md-menu-item>
 *      <md-button ng-click="doSomething()" aria-label="Do something">
 *        <md-icon md-menu-align-target md-svg-icon="call:phone"></md-icon>
 *        Do Something
 *      </md-button>
 *    </md-menu-item>
 *  </md-menu-content>
 * </md-menu>
 * </hljs>
 *
 * Sometimes we want to specify alignment on the right side of an element, for example
 * if we have a menu on the right side a toolbar, we want to right align our menu content.
 *
 * We can specify the origin by using the `md-position-mode` attribute on both
 * the `x` and `y` axis. Right now only the `x-axis` has more than one option.
 * You may specify the default mode of `target target` or
 * `target-right target` to specify a right-oriented alignment target. See the
 * position section of the demos for more examples.
 *
 * ### Menu Offsets
 *
 * It is sometimes unavoidable to need to have a deeper level of control for
 * the positioning of a menu to ensure perfect alignment. `md-menu` provides
 * the `md-offset` attribute to allow pixel level specificty of adjusting the
 * exact positioning.
 *
 * This offset is provided in the format of `x y` or `n` where `n` will be used
 * in both the `x` and `y` axis.
 *
 * For example, to move a menu by `2px` down from the top, we can use:
 * <hljs lang="html">
 * <md-menu md-offset="0 2">
 *   <!-- menu-content -->
 * </md-menu>
 * </hljs>
 *
 * ### Auto Focus
 * By default, when a menu opens, `md-menu` focuses the first button in the menu content.
 *
 * But sometimes you would like to focus another specific menu item instead of the first.<br/>
 * This can be done by applying the `md-autofocus` directive on the given element.
 *
 * <hljs lang="html">
 * <md-menu-item>
 *   <md-button md-autofocus ng-click="doSomething()">
 *     Auto Focus
 *   </md-button>
 * </md-menu-item>
 * </hljs>
 *
 *
 * ### Preventing close
 *
 * Sometimes you would like to be able to click on a menu item without having the menu
 * close. To do this, AngularJS Material exposes the `md-prevent-menu-close` attribute which
 * can be added to a button inside a menu to stop the menu from automatically closing.
 * You can then close the menu either by using `$mdMenu.close()` in the template,
 * or programatically by injecting `$mdMenu` and calling `$mdMenu.hide()`.
 *
 * <hljs lang="html">
 * <md-menu-content ng-mouseleave="$mdMenu.close()">
 *   <md-menu-item>
 *     <md-button ng-click="doSomething()" aria-label="Do something" md-prevent-menu-close="md-prevent-menu-close">
 *       <md-icon md-menu-align-target md-svg-icon="call:phone"></md-icon>
 *       Do Something
 *     </md-button>
 *   </md-menu-item>
 * </md-menu-content>
 * </hljs>
 *
 * @usage
 * <hljs lang="html">
 * <md-menu>
 *  <md-button ng-click="$mdMenu.open($event)" class="md-icon-button">
 *    <md-icon md-svg-icon="call:phone"></md-icon>
 *  </md-button>
 *  <md-menu-content>
 *    <md-menu-item><md-button ng-click="doSomething()">Do Something</md-button></md-menu-item>
 *  </md-menu-content>
 * </md-menu>
 * </hljs>
 *
 * @param {string} md-position-mode The position mode in the form of
 *           `x`, `y`. Default value is `target`,`target`. Right now the `x` axis
 *           also supports `target-right`.
 * @param {string} md-offset An offset to apply to the dropdown after positioning
 *           `x`, `y`. Default value is `0`,`0`.

 * Menu bars are containers that hold multiple menus. They change the behavior and appearence
 * of the `md-menu` directive to behave similar to an operating system provided menu.
 *

 *
 * ## Menu Bar Controls
 *
 * You may place `md-menu-items` that function as controls within menu bars.
 * There are two modes that are exposed via the `type` attribute of the `md-menu-item`.
 * `type="checkbox"` will function as a boolean control for the `ng-model` attribute of the
 * `md-menu-item`. `type="radio"` will function like a radio button, setting the `ngModel`
 * to the `string` value of the `value` attribute. If you need non-string values, you can use
 * `ng-value` to provide an expression (this is similar to how angular's native `input[type=radio]` works.
 *
 * <hljs lang="html">
 * <md-menu-bar>
 *  <md-menu>
 *    <button ng-click="$mdMenu.open()">
 *      Sample Menu
 *    </button>
 *    <md-menu-content>
 *      <md-menu-item type="checkbox" ng-model="settings.allowChanges">Allow changes</md-menu-item>
 *      <md-menu-divider></md-menu-divider>
 *      <md-menu-item type="radio" ng-model="settings.mode" ng-value="1">Mode 1</md-menu-item>
 *      <md-menu-item type="radio" ng-model="settings.mode" ng-value="1">Mode 2</md-menu-item>
 *      <md-menu-item type="radio" ng-model="settings.mode" ng-value="1">Mode 3</md-menu-item>
 *    </md-menu-content>
 *  </md-menu>
 * </md-menu-bar>
 * </hljs>
 *
 *
 * ### Nesting Menus
 *
 * Menus may be nested within menu bars. This is commonly called cascading menus.
 * To nest a menu place the nested menu inside the content of the `md-menu-item`.
 * <hljs lang="html">
 * <md-menu-item>
 *   <md-menu>
 *     <button ng-click="$mdMenu.open()">New</md-button>
 *     <md-menu-content>
 *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Document', $event)">Document</md-button></md-menu-item>
 *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Spreadsheet', $event)">Spreadsheet</md-button></md-menu-item>
 *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Presentation', $event)">Presentation</md-button></md-menu-item>
 *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Form', $event)">Form</md-button></md-menu-item>
 *       <md-menu-item><md-button ng-click="ctrl.sampleAction('New Drawing', $event)">Drawing</md-button></md-menu-item>

 * Please note that if you use `<md-tab-label>`, your content **MUST** be wrapped in the `<md-tab-body>` tag.  This
 * is to define a clear separation between the tab content and the tab label.
 *
 * This container is used by the TabsController to show/hide the active tab's content view. This synchronization is

/**
 * @ngdoc directive
 * @name mdTabs
 * @module material.components.tabs
 *
 * @restrict E
 *
 * @description
 * The `<md-tabs>` directive serves as the container for 1..n `<md-tab>` child directives to
 * produces a Tabs components. In turn, the nested `<md-tab>` directive is used to specify a tab
 * label for the **header button** and a [optional] tab view content that will be associated with
 * each tab button.
 *
 * Below is the markup for its simplest usage:
 *
 *  <hljs lang="html">
 *  <md-tabs>
 *    <md-tab label="Tab #1"></md-tab>
 *    <md-tab label="Tab #2"></md-tab>
 *    <md-tab label="Tab #3"></md-tab>
 *  </md-tabs>
 *  </hljs>
 *
 * Tabs supports three (3) usage scenarios:
 *
 *  1. Tabs (buttons only)
 *  2. Tabs with internal view content
 *  3. Tabs with external view content
 *
 * **Tab-only** support is useful when tab buttons are used for custom navigation regardless of any
 * other components, content, or views.
 *
 * <i><b>Note:</b> If you are using the Tabs component for page-level navigation, please take a look
 * at the <a ng-href="./api/directive/mdNavBar">NavBar component</a> instead as it can handle this
 * case a bit more natively.</i>
 *
 * **Tabs with internal views** are the traditional usages where each tab has associated view
 * content and the view switching is managed internally by the Tabs component.
 *
 * **Tabs with external view content** is often useful when content associated with each tab is
 * independently managed and data-binding notifications announce tab selection changes.
 *
 * Additional features also include:
 *
 * *  Content can include any markup.
 * *  If a tab is disabled while active/selected, then the next tab will be auto-selected.
 *
 * ### Explanation of tab stretching
 *
 * Initially, tabs will have an inherent size.  This size will either be defined by how much space is needed to accommodate their text or set by the user through CSS.  Calculations will be based on this size.
 *
 * On mobile devices, tabs will be expanded to fill the available horizontal space.  When this happens, all tabs will become the same size.
 *
 * On desktops, by default, stretching will never occur.
 *
 * This default behavior can be overridden through the `md-stretch-tabs` attribute.  Here is a table showing when stretching will occur:
 *
 * `md-stretch-tabs` | mobile    | desktop
 * ------------------|-----------|--------
 * `auto`            | stretched | ---
 * `always`          | stretched | stretched
 * `never`           | ---       | ---
 *
 * @param {integer=} md-selected Index of the active/selected tab
 * @param {boolean=} md-no-ink If present, disables ink ripple effects.
 * @param {boolean=} md-no-ink-bar If present, disables the selection ink bar.
 * @param {string=}  md-align-tabs Attribute to indicate position of tab buttons: `bottom` or `top`; default is `top`
 * @param {string=} md-stretch-tabs Attribute to indicate whether or not to stretch tabs: `auto`, `always`, or `never`; default is `auto`
 * @param {boolean=} md-dynamic-height When enabled, the tab wrapper will resize based on the contents of the selected tab
 * @param {boolean=} md-border-bottom If present, shows a solid `1px` border between the tabs and their content
 * @param {boolean=} md-center-tabs When enabled, tabs will be centered provided there is no need for pagination
 * @param {boolean=} md-no-pagination When enabled, pagination will remain off
 * @param {boolean=} md-swipe-content When enabled, swipe gestures will be enabled for the content area to jump between tabs
 * @param {boolean=} md-enable-disconnect When enabled, scopes will be disconnected for tabs that are not being displayed.  This provides a performance boost, but may also cause unexpected issues and is not recommended for most users.
 * @param {boolean=} md-autoselect When present, any tabs added after the initial load will be automatically selected
 * @param {boolean=} md-no-select-click When enabled, click events will not be fired when selecting tabs
 *
 * @usage
 * <hljs lang="html">
 * <md-tabs md-selected="selectedIndex" >
 *   <img ng-src="img/angular.png" class="centered">
