Thinking ahead about the PongGame class

We will be returning to this class constantly over the course of this project. What we will do in this chapter is get the fundamentals set up ready to add the game objects (the bat and ball) as well as collision detection and sound effects over the next two chapters.

To achieve this, first we will add a bunch of member variables, and then we will add some code inside the constructor to set the class up when it is instantiated/created by PongActivity.

After this, we will code a startNewGame method that we can call every time we need to start a new game, including the first time we start a game after the app is started by the user.
