/**
* Class Game - the main class of the "Zork" game.
*
* Author: Michael Kolling Version: 1.1 Date: March 2000
*
* This class is the main class of the "Zork" application. Zork is a very
* simple, text based adventure game. Users can walk around some scenery. That's
* all. It should really be extended to make it more interesting!
*
* To play this game, create an instance of this class and call the "play"
* routine.
*
* This main class creates and initialises all the others: it creates all rooms,
* creates the parser and starts the game. It also evaluates the commands that
* the parser returns.
