1.scene 전환 방법
2.scene 전환 액션  

전체 3개의 scene을 구성하면 각 scene당 Layer1 ,Layer2, Layer3 이 할당된다.
Layer1_Scene에서 Layer2_Scene로 전환될때는 push를 사용하고 이때 화면전환은
단순장면 전환 및 scene_action전환을 이용한다. 
Layer2_Scene에서 Layer1_Scene로 전환은 push의 반대 개념은 pop를 이용한다.


Layer2_Scene에서 Layer3_Scene로 전환 될때는 replace를 사용하고 이때 화면전환은
단순장면 전환 및 scene_action전환을 이용한다.
Layer3_Scene에서 pop를 이용하면 Layer1_Scene로 이동한다.

            CCMenuItemFont item3 = CCMenuItemFont.item("Quit", this, "onQuit");
