/*

Usage is very simple. Firstly, you will need to include a javascript library at the top of your html file like this ...

<script language='javascript' src='popcalendar.js'></script>
After which, put the following line inside the onclick event of a button, 

popUpCalendar(this, this, "d mmm yyyy")
The first "this" in the parameter list refers to the trigger control (in this case the button). The second "this" refer to the control to hold the value of the date, which is the same button in this case. The third parameter refers to the date format. The date format can have three types of separators: hyphen(-), space( ), or slash(/), but must be consistent in their usage. E.g. 
	d/m/yyyy

The acceptable tokens are :- 
	d - date
	dd - date (padded with 0 if less than 10)
	m - month (in numbers)
	mm - month (in numbers, padded with 0 if less than 10)
	mmm - month (in words)
	yyyy - year 
	
The default value you place in the date container must be the same format as the format you specified, otherwise, hmm... I also dunno what will happen. Maybe you test it out and email me :) 

To fix the position of the popup calendar, you can change the values of the variables fixedX and fixedY. Setting them to -1 will make them appear just below the trigger control.

To start the week on Monday, just amend the startAt variable at the beginning of the javascript file. Assigning a value of 0 will start the week on Sunday, and 1 will start the week on Monday. 

To show week numbers as well (for compliance to ISO-8601 standard), change the showWeekNumber variable to 1. 

[ new ] To hide today's date, change the showToday variable to 0. 

[ new ] An example to translate into another language : 

	<script language="JavaScript">
	<!--
	addHoliday(25,12,0, "Weihnachten")
	addHoliday(1,1,0, "Neujahr")

	monthName = new
	Array("Januar", "Februar", "März", "April", "Mai", "Juni", "Juli", "August", "S eptember", "Oktober", "November", "Dezember")
	gotoString = "Zum aktuellen Monat"
	todayString = "Heute ist"
	weekString = "KW"

	startAt = 1
	dayName = new Array ("Mo","Di","Mi","Do","Fr","Sa","So")

	//-->
	</script> 

[ new ] To specify a image path for the required images, set imgDir variable to contain the string of the path. 


Defining Holidays

To insert a holiday, use the following javascript function : 
addHoliday (date, month, year, description)
If the year is set to 0 (zero), all the years with that date will be defined as a holiday. For example, 
addHoliday(25,12,0, "Christmas Day")
