Get X,Y,T, Initial Values, Boundry conditions

Create a data space X x Y
Assign initial value
print initial value and the text' initial value'

do while turns<T:
    check data space according to boundry conditions
    create new data space according to rules and old data space.
    replace dataspace
    print data space.
