 Functionality presents an interactive calendar for a use to pick a date from.

 The current supported date format is 'mm/dd/yyyy'. Originally, the calendar was drawn in 

 a popup window(some of that code is left commented out.  I decided to create a calendar drop-down with similiar functionality to the 

 date picker used by expedia.com ie the calendar automatically is positioned below the object it is called from.

 

 To utilize this functionality for a text box, a call would look something like ->

 <INPUT id=cmdDisplayCalEnd  onclick="javascript:buildCal(frmDateSelect.txtEndDate);" name=cmdDisplayCalEnd type=button style="HEIGHT: 22px; WIDTH: 19px" value=...>

 

*/

/*  

	Functions for validating dates

	var newformat = {date:{d:0,m:1,y:2},time:{h:0,m:1}}; is the format = dd/mm/yyyy

	var newformat = {date:{m:0,d:1,y:2},time:{h:0,m:1}}; is the format = mm/dd/yyyy
