// -------------------------------------------------------------------------------
// Called From: all of the pages that use the standard subnavigation
// Purpose: The page starts with two functions: PG_showSubNav and PG_hideSubNav.  Each 
//			function takes in the object name of the menu. 
//			Depending on the function called and the browser being used, 
//			the visibility state of the dropdown menu is altered using the 
//			appropriate DOM.
//
//			The page then preloads all of the images that will be used in the  
//			horizontal navigation bar.
//
//          The page then loads all of the subnavigation text into each dropdown menu.  
//			Each array consists of the array name, the location of the dropdown menu 
//			(pixels from the left), and the width of the menu.  This is followed by 
//			a varying number of text links and the address (URL) of each link.
//
//			The function PG_setUpMenus then creates the dropdown menu using the information  
//			from the arrays.  This function takes 5 parameters: the background color of 
//          the menu, the rollover background color of the menu, the text color of 
//          the menu, the rollover text color, and the color of the line separating 
//          each link in the menu.
