Notice that there is an abstract class named AbstractCell, and that there are three derived classes: ConwayCell, NeverAliveCell, and AlwaysAliveCell. Examine the way that the derived classes implement the abstract member functions in AbstractCell. The ConwayCell implements the standard behavior of a call in Conway$$s Game of Life.

For this assignment you only need to implement and test two new classes. You will create two different cells, derived from AbstractCell.
