 * 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
 *
