Design a simulator for an artificial life game with goats and grass

Step 1: compile source code

make

Step 2: specify three optional parameters

./ALifeTest_ <passes> <display> <seed>

For example, ./AlifeTest_ 1000 100 1234 means that the simulation will run for 1000 passes and display the world once every 100 passes with the seed of 1234 for the random number generator. If the user specifies zero passes, or a negative number, the program defaults to a single pass.
