Tic Tac Toe -> Lights out

Tic-Tac-Toe to Lights Out.

For this project, we were tasked with converting a Tic-Tac-Toe game to Lights Out. This was a code challenge to make it as simple as possible. In this case, I decided to go with an algorithmic approach to figuring out which symbols need to be toggled. Instead of a bunch of if-else statements.
