Added command line options
Cleaned up (left debugging print statement when parsing options)
Renamed tictactoe.py to tictactoe. Don't need to have an extension on Linux (like MS Windows needs) because of the shebang, so might as well have a better name
Added compiled PYC files to git list of files to ignore

Added player classes, still need to implement code for a human or
computer turn
Updated Player classes to set the mark (X or O) depending on who's first

Added board class (draws the board currently, still need to add other
functionality)
Added methods to the board class to determine end of game, who's the winner, or if it was a tie

Updated Player class (needed the board instance to make a turn)

Added intro (with instructions)
Added more functionality to the board class to get information

Added 'turn' code for Human (prompts for and verifies position to mark)

Added 'turn' code for Computer (implemented basic win strategy, need to
enhance normal strategy)
Turn rules for computer are done (with minimal testing). Works when computer is first player. Needs more testing and when the human goes first.
Added 'end of game' messages
Fixed a bug relating to finding the winning mark (X or O)
Fixed bug relating to matching a specified # of marks in a row, column, or diagonal
Fixed bug when human went first (board was drawn twice in a row)
