/**
 * JS file using jQuery to add necessary styling to HTML leftnav menu's for VeriSign sites
 * Author: E Grobler
 * Version: 1.2
 * Date: 16/02/2010
 * 
 * Version 1.3  :o)
 * Author: Rob Perez
 * 
 * Added noClicksHere to disable cursor, underlining, and clicking when the user is on the highlighted page
 * while preserving existing "parental" clicking.
 * 
 * Date: April 5, 2010
 * 
   Version 1.3.1  :o)
 * Author: Rob Perez
 *  
 *  navigation now requires a function call rather than happening on ready()  for improved (perception of) performance
 *  
 *  generateLefNav()
 *  
 *  called immediately after the nav is available
 * 

 * Date: April 6, 2010
 * 
 * Version 1.3.2 
 * Author: Rob Perez
 * 
 * 	Set a flag at the beginning of generateLeftNav to disable expansion of the nav if desired.
 * 
 * Usage:
 *  Somewhere prior to including the nav, set the noLeftNavExpansion var to true:
 *  
 * 			<script type="text/javascript">
					noLeftNavExpansion = true;
				</script>
 * 
 * Date: May 17, 2010
