This is the new foldoutmenu, with more levels!
This is in some ways a rather advanced menu so please read every
note in this script and in the comments in the page to understand how
it works.

NOTE: if you change the position of menuCont from absolute to relative, 
you can put the menu in a table. HOWEVER it will no longer work in netscape 4.
If you wish to support netscape 4, you have to use absolute positioning.
