+ PageHandle is a class that renders the actual page handles and reacts to
+ click events for pagination.
+
+ This class acts in two modes - control or discrete page handle modes. If
+ one of the `is*` flags is `true`, an instance of this class is under
+ control page handle mode. Setting a `pageIndex` to an instance of this
+ class under control mode has no effect and the correct page index will
+ always be inferred from the `is*` flag. Only one of the `is*` flags should
+ be set to `true` at a time. For example, an instance of this class cannot
+ simultaneously be a rewind control and a fast forward control. A `label`
+ and a `title` function or a string are required to be passed to the
+ constuctor under this mode. If a `title` function is provided, it __MUST__
+ accept a hash parameter `data`, which contains a key `label`. Its result
+ will be used to render the generated anchor's title attribute.
+
+ If all of the `is*` flags is set to `false`, which is the default, an
+ instance of this class will be in discrete page handle mode. An instance
+ under this mode requires the `pageIndex` to be passed from the constructor
+ as an option and it __MUST__ be a 0-based index of the list of page numbers
+ to render. The constuctor will normalize the base to the same base the
+ underlying PageableCollection collection instance uses. A `label` is not
+ required under this mode, which will default to the equivalent 1-based page
+ index calculated from `pageIndex` and the underlying PageableCollection
+ instance. A provided `label` will still be honored however. The `title`
+ parameter is also not required under this mode, in which case the default
+ `title` function will be used. You are encouraged to provide your own
+ `title` function however if you wish to localize the title strings.
+
+ If this page handle represents the current page, an `active` class will be
+ placed on the root list element.
+
+ If this page handle is at the border of the list of pages, a `disabled`
+ class will be placed on the root list element.
+
+ Only page handles that are neither `active` nor `disabled` will respond to
+ click events and triggers pagination.
