Overview

GAME CLASS. This class takes care of getting user input from the user, passing it to the appropriate class for error checking, starting the game, and ending the game. A Game object must be created. The user must then call the initialize function, pass it the parameters, and then call start. Those three steps are all that is necessary to start the game.
