I changed the pattern of the tiles and added the docstring to the function.

Checkpoint 3:
- I will definitely use docstrings in the future.  I will use them because they are helpful in showing another person what each function does.  Also, when I am debugging my code it will be helpful if I know what each function is supposed to be doing.
