public class Spatial

extends javax.swing.JPanel

Provides the ability to evolve a two dimensional grid of Prisoners. This class allows for spatial interactions, that is, a Prisoner can only interact (play IPD or mate) with the Prisoners in the cells surrounding it. The edges of the grid 'overlap' so each Prisoner has neighbours on all sides. The production of the next generation may be via simple evolution or genetic evolution. This class also allows such a grid to be represented graphically.
