SpryMenuBar.js
This file handles the JavaScript for Spry Menu Bar.  You should have no need
to edit this file.  Some highlights of the MenuBar object is that timers are
used to keep submenus from showing up until the user has hovered over the parent
menu item for some time, as well as a timer for when they leave a submenu to keep
showing that submenu until the timer fires.

      If you have Celiac Disease or are Gluten-Intolerant (and are over 21), stop what you are doing right now. Your prayers for a great tasting gluten-free beer have finally been answered, or at least are in the process of being answered. Think of it as a delay in the mailroom. All of those nights when your friends were taunting you with the ice cold, delicious, golden liquid that gives courage to even the most faint of heart are quickly coming to an end. Your desire to enjoy a "cold one" without having a gut-wrenching reaction should be fullfilled by the end of the summer. The CSU iGEM team is working on producing a "gluten-free" beer that can be brewed from wheat or barley so you can savor that same great taste you know and love. So cross your fingers, bust out your lucky rabbits foot, and watch out for black cats because we are gearing up for something big, and it has never been done before.
