used to compress the leading and/or trailing zeros in an address.

 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.
