using a whacky hack to create single instances of several classes at once.

autoSingletonMaker.as

		/**
		 * creates a single instance of each state and stores them in a dictionary of states. 
		 */
		// OH, HACKY! .... OR BRILLIANT?
		protected function initializeStates():void {
			allStates = new Dictionary( false );
									     //This vector contains several state classes i want to instantiate.
			var stateClasses:Vector.<Class> = new Vector.<Class> ([MainMenuState, CreditsState, GameplayState]); 
			
			for each ( var stateClass:Class in stateClasses) {
				allStates[stateClass] = new stateClass();
			}
		}
		
		/**
		 * Gets the instance of the state based on the class.
		 */
		public function getState(stateClass:Class):IGameState {
			return allStates[stateClass] as IGameState;
