text: //** Smooth Navigational Menu- By Dynamic Drive DHTML code library: http://www.dynamicdrive.com
  //** Script Download/ instructions page: http://www.dynamicdrive.com/dynamicindex1/ddlevelsmenu/
  //** Menu created: Nov 12, 2008
  
  //** Dec 12th, 08" (v1.01): Fixed Shadow issue when multiple LIs within the same UL (level) contain sub menus: http://www.dynamicdrive.com/forums/showthread.php?t=39177&highlight=smooth
  
  //** Feb 11th, 09" (v1.02): The currently active main menu item (LI A) now gets a CSS class of ".selected", including sub menu items.
  
  //** May 1st, 09" (v1.3):
  //** 1) Now supports vertical (side bar) menu mode- set "orientation" to 'v'
  //** 2) In IE6, shadows are now always disabled
  
  //** July 27th, 09" (v1.31): Fixed bug so shadows can be disabled if desired.
  //** Feb 2nd, 10" (v1.4): Adds ability to specify delay before sub menus appear and disappear, respectively. See showhidedelay variable below
  
  //** Dec 17th, 10" (v1.5): Updated menu shadow to use CSS3 box shadows when the browser is FF3.5+, IE9+, Opera9.5+, or Safari3+/Chrome. Only .js file changed.
