def displayDistributionsOverPositions(self, distributions):
    """
    Overlays a distribution over positions onto the pacman board that represents
    an agent's beliefs about the positions of each agent.

    The arg distributions is a tuple or list of util.Counter objects, where the i'th
    Counter has keys that are board positions (x,y) and values that encode the probability
    that agent i is at (x,y).

    If some elements are None, then they will be ignored.  If a Counter is passed to this
    function, it will be displayed. This is helpful for figuring out if your agent is doing
    inference correctly, and does not affect gameplay.
