/*  Authors: Xiaori Hu & Lasse Annola
 *	MainMenu includes the submenus(background, proptype, scene, clearMenu, clearEntity) , besides, the prop also has four submenus (element, object, manmade, effect)
 *  itself.
 *  When you click the buttons ( background, proptype, scene) on the interface of MainMenu, it will popup the corresponding submenu at right side of MainMenu
 *  when you click the button (clearMenu) on the interface of MainMenu, it will hind the submenu in the screen
 *  when you click the button (clearEntity) on the interface of MainMenu, it will clear all the entities in the scene. 
 *  KNOWN BUG: When holding z,x,c or space for a long period of time to move an entity GUI crashes. Fixed by adding MainMenu.js gui script into a separate entity
 *    from PropsScript.js.
