 Line 31. The Application.LoadLevel method is used to reload the active level,
effectively restarting the game.
 Line 37. Application.Quit is called to terminate the game. The code, as given
in line 37, only works when the game is running as a stand-alone application,
and not in the editor. For more information, see the following note.
