    Attributes:
    X,Y : horizontal and vertical size of the board
    state : dictionary mapping (x,y) to 0 or 1

    Methods:
    display(update_board) -- If update_board is true, compute the
                             next generation.  Then display the state
                             of the board and refresh the screen.
    erase() -- clear the entire board
    makeRandom() -- fill the board randomly
    set(y,x) -- set the given cell to Live; doesn't refresh the screen
    toggle(y,x) -- change the given cell from live to dead, or vice
                   versa, and refresh the screen display
