+/*
+Create a "Choose Your Own Adventure" game using an object. In these kind of
+games, the player is in a room and can move to other rooms to the north, east,
+south or west.
+
+To start the game, run this file with Node as usual. To stop the game, press
+Ctrl-C.
+
+It has a currentRoom property to store which room the player is in.
+
+Give your object methods for:
+
+- Starting the game in the correct room when passed a room name parameter
+- Moving the player to another room when passed a direction parameter
+
+The functionality for running a game has been provided for you. It first prompts
+the player to enter the starting room. Then it will ask players to to type in a
+direction (north/east/south/west) that they want to move in.
+
+An object containing one object per room has been provided for you. Take your
+time to read it carefully. The rooms look something like this:
++-----------+-----------+
+|           |           |
+|   Hall    | Classroom |
+|           |           |
++-----------------------+
+|           |
+|  Library  |
+|           |
++-----------+
+
+----------------------------------------------------------
+
+Stretch goal: what happens if you try to move in a direction that the current
+room doesn't allow? For example if you are in the Classroom and you try to move
+east? If there is a bug in your code, try to fix it.

+    // to start in.
+    // Finish the function so that the currentRoom property is set to the room
+    // object for the correct room.
+    //
+    // Hint: the only valid rooms are "hall", "classroom" and "library".
+  },
+
+  move: function (direction) {
+    // This function is called with the direction that the player wants to move.
+    // Finish the function so that the currentRoom property is updated with new
+    // room in the direction that the player wants to move in.
+    //
+    // Hint: the room objects have north/east/south/west methods which return
+    // a new room object that is in the relevant direction.
