Pop-up Calendar v5 - http://is.rc.deere.com/webworks/CalendarV5

Version 4 
	Added
	 	* SimpleDateFormat 
		* function makeCalendarForDay
		* Some Validation Goodies
			function isNDaysApart(start,end,n)
			function changeDay(selectedDay,n,maxDate)
Version 5
	Added
		* function clearCalendar() - which calls the function window.customDisplay 
					 	(if it exists) after the clear button is pressed
		* function makeCalendarForDays - to take an array of days
Version 5.1
	Added 
		* function posX(obj) and posY(obj) to get the current position of a form element
		* open the Calendar over the current form element instead of some arbitrary location
Version 5.1.1
	Added
		* in openCalendar(...) I now account for scrolling for posX(obj) and posY(obj)
