* Class Room - a room in an adventure game.
*
* This class is part of the "World of Zuul" application.
* "World of Zuul" is a very simple, text based adventure game.
*
* A "Room" represents one location in the scenery of the game. It is
* connected to other rooms via exits. The exits are labelled north,
* east, south, west. For each direction, the room stores a reference
* to the neighboring room, or null if there is no exit in that direction.
