* This class is the main class of the "World of Zuul" application.

* to make it more interesting!
*
* To play this game, create an instance of this class and call the "play"
* method.
*
* This main class creates and initialises all the others: it creates all
* rooms, creates the parser and starts the game. It also evaluates and
* executes the commands that the parser returns.
