 The ''BingoCell'' class would be a subclass of {{ ::cell.java |Cell}}  that would add the attributes of a number and a font. It will have its own draw method that can draw its number.  Here is a hint on how to do one of the Constructors: The ''BingoCell'' class would be a subclass of {{ ::cell.java |Cell}}  that would add the attributes of a number and a font.

 +  - a ''size'' for the of the BingoBoard.  The board will be square, because of margins, the size of the BingoCells would be a fraction of the size. 
 +  - a method ''contains(int number)'' that returns true if the number is in board, and false otherwise.
