// MENU SYSTEM JAVA SCRIPT
// This is a java script menu system. It uses functions to build a menu system up that is easy to change or modify
// It also checks for different browsers and adjusts the positioning to accomodate the differences in browsers.
// A menu system is created/built up and then positioned relatively to an existing object. This is done upon load and resize events.
