/* Date Picker */
	/**
		This is a JavaScript library that will allow you to easily add some basic DHTML
		drop-down datepicker functionality to your Notes forms. This script is not as
		full-featured as others you may find on the Internet, but it's free, it's easy to
		understand, and it's easy to change.
		
		You'll also want to include a stylesheet that makes the datepicker elements
		look nice. An example one can be found in the database that this script was
		originally released with, at:
		
		http://www.nsftools.com/tips/NotesTips.htm#datepicker
		
		I've tested this lightly with Internet Explorer 6 and Mozilla Firefox. I have no idea
		how compatible it is with other browsers.
		
		version 1.5
		December 4, 2005
		Julian Robichaux -- http://www.nsftools.com
		
		HISTORY
		--  version 1.0 (Sept. 4, 2004):
		Initial release.
		
		--  version 1.1 (Sept. 5, 2004):
		Added capability to define the date format to be used, either globally (using the
		defaultDateSeparator and defaultDateFormat variables) or when the displayDatePicker
		function is called.
		
		--  version 1.2 (Sept. 7, 2004):
		Fixed problem where datepicker x-y coordinates weren't right inside of a table.
		Fixed problem where datepicker wouldn't display over selection lists on a page.
		Added a call to the datePickerClosed function (if one exists) after the datepicker
		is closed, to allow the developer to add their own custom validation after a date
		has been chosen. For this to work, you must have a function called datePickerClosed
		somewhere on the page, that accepts a field object as a parameter. See the
		example in the comments of the updateDateField function for more details.
		
		--  version 1.3 (Sept. 9, 2004)
		Fixed problem where adding the <div> and <iFrame> used for displaying the datepicker
		was causing problems on IE 6 with global variables that had handles to objects on
		the page (I fixed the problem by adding the elements using document.createElement()
		and document.body.appendChild() instead of document.body.innerHTML += ...).
		
		--  version 1.4 (Dec. 20, 2004)
		Added "targetDateField.focus();" to the updateDateField function (as suggested
		by Alan Lepofsky) to avoid a situation where the cursor focus is at the top of the
		form after a date has been picked. Added "padding: 0px;" to the dpButton CSS
		style, to keep the table from being so wide when displayed in Firefox.
		
		-- version 1.5 (Dec 4, 2005)
		Added display=none when datepicker is hidden, to fix problem where cursor is
		not visible on input fields that are beneath the date picker. Added additional null
		date handling for date errors in Safari when the date is empty. Added additional
		error handling for iFrame creation, to avoid reported errors in Opera. Added
		onMouseOver event for day cells, to allow color changes when the mouse hovers
		over a cell (to make it easier to determine what cell you're over). Added comments
		in the style sheet, to make it more clear what the different style elements are for.

		This is the main function you'll call from the onClick event of a button.
		Normally, you'll have something like this on your HTML page:
		
		Start Date: <input name="StartDate">
		<input type=button value="select" onclick="displayDatePicker('StartDate');">
		
		That will cause the datepicker to be displayed beneath the StartDate field and
		any date that is chosen will update the value of that field. If you'd rather have the
		datepicker display beneath the button that was clicked, you can code the button
		like this:
		
		<input type=button value="select" onclick="displayDatePicker('StartDate', this);">
		
		So, pretty much, the first argument (dateFieldName) is a string representing the
		name of the field that will be modified if the user picks a date, and the second
		argument (displayBelowThisObject) is optional and represents an actual node
		on the HTML document that the datepicker should be displayed below.
		
		In version 1.1 of this code, the dtFormat and dtSep variables were added, allowing
		you to use a specific date format or date separator for a given call to this function.
		Normally, you'll just want to set these defaults globally with the defaultDateSeparator
		and defaultDateFormat variables, but it doesn't hurt anything to add them as optional
		parameters here. An example of use is:
		
		<input type=button value="select" onclick="displayDatePicker('StartDate', false, 'dmy', '.');">
		
		This would display the datepicker beneath the StartDate field (because the
		displayBelowThisObject parameter was false), and update the StartDate field with
		the chosen value of the datepicker using a date format of dd.mm.yyyy
