| * shows you what one can do with the calendar, while in the same time |
| * providing a quick and simple method for setting it up. If you need |
| * exhaustive customization of the calendar creation process feel free to |
| * modify this code to suit your needs (this is recommended and much better |
| * than modifying calendar.js itself). |

| /** |
| * This function "patches" an input field (or other element) to use a calendar |
| * widget for date selection. |
| * |
| * The "params" is a single object that can have the following properties: |
| * |
| * prop. name | description |
| * ------------------------------------------------------------------------------------------------- |
| * inputField | the ID of an input field to store the date |
| * displayArea | the ID of a DIV or other element to show the date |
| * button | ID of a button or other element that will trigger the calendar |
| * eventName | event that will trigger the calendar, without the "on" prefix (default: "click") |
| * ifFormat | date format that will be stored in the input field |
| * daFormat | the date format that will be used to display the date in displayArea |
| * singleClick | (true/false) wether the calendar is in single click mode or not (default: true) |
| * firstDay | numeric: 0 to 6. "0" means display Sunday first, "1" means display Monday first, etc. |
| * align | alignment (default: "Br"); if you don't know what's this see the calendar documentation |
| * range | array with 2 elements. Default: [1900, 2999] -- the range of years available |
| * weekNumbers | (true/false) if it's true (default) the calendar will display week numbers |
| * flat | null or element ID; if not null the calendar will be a flat calendar having the parent with the given ID |
| * flatCallback | function that receives a JS Date object and returns an URL to point the browser to (for flat calendar) |
| * disableFunc | function that receives a JS Date object and should return true if that date has to be disabled in the calendar |
| * onSelect | function that gets called when a date is selected. You don't _have_ to supply this (the default is generally okay) |
| * onClose | function that gets called when the calendar is closed. [default] |
| * onUpdate | function that gets called after the date is updated in the input field. Receives a reference to the calendar. |
| * date | the date that the calendar will be initially displayed to |
| * showsTime | default: false; if true the calendar will include a time selector |
| * timeFormat | the time format; can be "12" or "24", default is "12" |
| * electric | if true (default) then given fields/date areas are updated for each move; otherwise they're updated only on close |
| * step | configures the step of the years in drop-down boxes; default: 2 |
| * position | configures the calendar absolute position; default: null |
| * cache | if "true" (but default: "false") it will reuse the same calendar object, where possible |
| * showOthers | if "true" (but default: "false") it will show days from other months too |
| * |
| * None of them is required, they all have default values. However, if you |
| * pass none of "inputField", "displayArea" or "button" you'll get a warning |
| * saying "nothing to setup". |
