 * Code modified on 2011-Jan-09 by Dwayne Collins						  *
 * This code was modified to work with the multi-level menus specoific to *
 * this site. It is currently set to work with menus up to three levels   *
 * and could be modified for further sub-menus by increasing the          *
 * .parentNode IF and className statements according to the pattern.      *
 * The original code for this was found at:								  *
