// Purpose	: Game of life applet , which includes a board which the user
//              : would change by turning the cells into dead or alive ones, 
//              : then by choosing a cycles , they will go through that number 
//              : of cycles and each time through a set of rules , cells would 
//              : die, be born, stay alive or stay dead. The end results are
//              : always facinating
