//This is the file that shows and hides navigation items based on a user's preferences.
//This file also makes all of the javascript unobtrusive in case a user has javascript turned off.
//By default, all elements of the navigation are shown, and the customize button is hidden. 
//As a result, if a user has javascript disabled, they will have no problems accessing content.
//If the user does have javascript enabled, then the first portion of showNav() hides submenus, 
//and shows the customize nav button.
