Initial checkin of tictactoe game
Fleshed out tictactoe bunch more
Add the winning player name to the output 

- Fixed the class + naming of the AI vs AI setup
Refactored naming to be more clear
Added enumerable to Board so can easily find possible moves
Add dumb AI…need to fill out smarter AI
Changed first position on board to be 0 instead of 1
Got pick winning move if possible
Impletemented stop_other_player_winning
Renames board.board to board.places, so no naming conflict
Added cloning method to Board
Woot! Got minimax algorithm working

- Bit slow as not doing AlphaBeta pruning, but good enough
Removed specs. Didn’t really use so don’t pretend
Separated out player and board classes
Separated out human and ai player classes into own files
