        Performs the actions for a prey entity

        For prey the rules are:
            1. At each chronon, a prey moves randomly to one of the adjacent unoccupied
               squares. If there are no free squares, no movement takes place.
            2. Once a prey has survived a certain number of chronons it may reproduce.
               This is done as it moves to a neighbouring square,
               leaving behind a new prey in its old position.
               Its reproduction time is also reset to zero.
