//displays a drop menu by making a div element visible as a sub menu to 2 levels.  
//base menu link id must be 'menu' + unique id
//1st level menu div id must be named 'submenu' + the base menu link id
//1st level menu link id must be 'menu' + unique id
//2nd level menu div id must be named 'subsubmenu' + the 1st level menu link id
//

//eg.   <!-- main menu -->
//		<div id="Menu">
//			<a id="menuItem1" onmouseover="DM_i=2; showMenu('Item1')" onmouseout="DM_i=1; holdMenu()">
//				Base Menu Item 1
//			</a>
//		</div>
//		<!-- 1st level menu -->
//      <div id="submenuItem1" style="visibility:hidden" onmouseover="DM_i=2; showMenu('Item1');" onmouseout="DM_i=1; holdMenu();">
//			<a id="submenuItem1.1 onmouseover="DM_i=2; DM_subi=2; showMenu('Item1'); showSubMenu('Item1.1');" onmouseout="DM_i=1; DM_subi=1; holdMenu(); holdSubMenu();">Item1.1</a>          
//			<a>1st level menu Item1.2</a>

//      <!-- 2nd level menu -->
//      <div id="subsubmenuItem1.1" style="visibility:hidden" onmouseover="DM_i=2; DM_subi=2; showMenu('Item1'); showSubMenu('Item1.1');" onmouseout="DM_i=1; DM_subi=1; holdMenu(); holdSubMenu();">
