An important goal for this assignment will be to organize your code so that it follows the model-view-controller (mvc) architecture. if you followed the structure specified in a1, you should already have a "controller": the game class containing the play() method. the gameworld class becomes the "data model", containing the collection of game objects and other game state information. you are also required to add two classes acting as "views": a score view which will be graphical, and a map view which for now will retain the text-based form generated by the ‘m’ command in a1 (in a3 we will replace the text-based map with an interactive graphical map).
