For all of the template methods, they should return None unless they return a new State to switch the engine to.

Template Method - Initialize the state, called once the first time a state is selected.

State is responsible for calling pygame.display.flip() or whatever.

Template Method - called at the beginning of State.run() to initialize things.

Game.init()

Template Method - called once per frame, usually for timer purposes.

return a True value if the event is captured and does not need to be passed onto the current state
