code updated
added switch case to process arc4random; switch case ready for testing
locked down randomizer switch case into its own method; appears to be both functional and stable
added missing check; switch cases do not see capible of accessing array contents at a case index..?
cleaned block checking method to have win check made once at the end of the function rather on multiple lines
now only winCheck method can determine a win/loss; increased stability to prevent scenario moves and attemptWinningMove from making that determination
switch case added into tileSelected method
made amazing fix to fillInAnySquare method; only has to fast enumerate now
optimized winCheck to break loop upon finding win
all AI checks now have a break funtion in place
cleaned up winCheck calls in preset move scenarios as well as replaced additional if else statements with switch case in GamePlayViewController
ready to merge with master
