Many Things
--Allowed the visualisation to be quitable.
--Added an end-of-game check on whether there were any prey left.
--Added a mechanism for removing prey which were on the same square as a
predator.
--If a piece moved off a piece it was covering, the covered piece would
disappear, fixed this by updating all pieces after each piece is moved.
--Added a toString and equals method to Point.
