#Game of Life simulation
#Author:  James Tam
#Version: June 6, 2020
#This version of the program initializes the oldWorld (during the turn)
#and the newWorld (appearance of the world after the turn) as well as
#displaying the two versions side by side. Since the original state of
#the biosphere was empty the state of the new state is correct. However,
#no rules of births and deaths was applied in this version of the
#simulation.
