 ActiveMenu.js
 This file handles the JavaScript for determining which page has been selected
 and setting that Main/Sub Link to appear 'active' in the menu bar. Each link
 has been given a unique 'id' that is used to compare it's 'href' value against
 the current page's 'url'.

 Remeber when adding or removing links in the navigational bar to add or remove
 the appropriate variables from the arrays below.
