Modifications - 12/20/2005
- Library renamed to navmenu.js from menu.js; menu.js already existed on the web site.
- variable horizontal removed and the second call to the function simpleMenu removed;
  not needed since we are only using the vertical menu option
 - added 4 calls to simpleMenu because there will be 5 instances of the menu on the page.
 
Modifications - 1/7/2006
- Added two functions to hide any <select> tags for input forms. In IE 5.x and greater,
 these elements ignore any z-index property assign to them. In order to stop them from
 appearing on top of the expanded menu they are hidden when the menu is used.
 (Also see the onmouseover and onmouseout events for the <A> tags in the menu.
