/**
* 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)
* mondayFirst | (true/false) if true Monday is the first day of week, Sunday otherwise (default: true)
* align | alignment (default: "Bl"); 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"
*
* 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".
