I added the retro lab code, made 4 python files, and gave the player the ability to move left, right, up, and down.

A recent success that I am proud of is that I was able to give the player the ability to move up, down, left, and right.  When implementing the ability to move up and down it seemed that the code was opposite of what I expected it to be.  I was able to figure out how to implement it the correct way.
