  2.  * Class Room - a room in an adventure game.
  3.  *
  4.  * This class is part of the "World of Zuul" application.
  5.  * "World of Zuul" is a very simple, text based adventure game.  
  6.  *
  7.  * A "Room" represents one location in the scenery of the game.  It is
  8.  * connected to other rooms via exits.  The exits are labelled north,
  9.  * east, south, west.  For each direction, the room stores a reference
  10.  * to the neighboring room, or null if there is no exit in that direction.
