+/**
+ * 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".
