Hi guys, this is the second version that I sent. In this opportunity I completed all the requirements:

• Make sure turns are passed between the AI and the real player: I'm not sure if I did the best way possible, but the turn is being passed between the player and the AI
• Come up with a way to represent the Tic tac toe algorithm in code: Done
• Make sure no piece can be put on top of another piece: Done
• Check for a win-lose or tie condition: Done
• The player turn: I added this little feature, at the top left corner you will see the current player turn, even though I'm having a little trouble with the text.

I also have a couple of ToDos:

• Implement AiLevel, to differentiate between easy and hard
• I would like to refactor a little more the code, I think I can separate the logics, for instance separate the management of the player and turns, from the management of the UI
• A couple of refactor in some methods
