ALERT!
If you are creating a custom event class that extends Event, remember
that it s very important to override the clone function. By overriding the

clone function, you allow the event to be redispatched if needed.

The MemoryGame Class (the Game Engine)
And now for the core of this chapter and the engine of the game
itself: the MemoryGame class. The MemoryGame class uses an
array of images that are passed in to create, shuffle, and deal the
cards. It also handles user interactions, checks for card matches/
mismatches and game completions, and sends out a notification of
each event using the MemoryGameEvent class.
