+/**
+ *  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: false)
+ *   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
+ *
+ *  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".
