 *  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".

  <h1>Sample for the multiple dates feature</h1>

  <p>
    Starting version 0.9.7,
    the calendar is able to handle multiple dates selection, in either
    flat or popup form.  For this to happen one needs to pass the
    "<tt>multiple:&nbsp;true</tt>" parameter to
    <tt>Calendar.setup</tt> and to install an <tt>onUpdate</tt>
    handler that watches for modifications.
  </p>

  <a id="trigger" href="#">[open calendar...]</a>

  <div id="output"></div>

  <script type="text/javascript">
  //
    // the default multiple dates selected, first time the calendar is instantiated
    var MA = [];

    function closed(cal) {

      // here we'll write the output; this is only for example.  You
      // will normally fill an input field or something with the dates.
      var el = document.getElementById("output");

      // reset initial content.
      el.innerHTML = "";

      // Reset the "MA", in case one triggers the calendar again.
      // CAREFUL!  You don't want to do "MA = [];".  We need to modify
      // the value of the current array, instead of creating a new one.
      // Calendar.setup is called only once! :-)  So be careful.
      MA.length = 0;

      // walk the calendar's multiple dates selection hash
      for (var i in cal.multiple) {
        var d = cal.multiple[i];
        // sometimes the date is not actually selected, that's why we need to check.
        if (d) {
          // OK, selected.  Fill an input field.  Or something.  Just for example,
          // we will display all selected dates in the element having the id "output".
          el.innerHTML += d.print("%A, %Y %B %d") + "<br />";

          // and push it in the "MA", in case one triggers the calendar again.
          MA[MA.length] = d;
        }
      }
      cal.hide();
      return true;
    };

    Calendar.setup({
      align      : "BR",
      showOthers : true,
      multiple   : MA, // pass the initial or computed array of multiple dates to be initially selected
      onClose    : closed,
      button     : "trigger"
