Ruby command line tic-tac-toe game.

The tic-tac-toe application accompanies an online tutorial for building object-oriented games with Ruby. Here is a link to the online tutorial: http://wp.me/p3sWrq-3P

I plan to create a pre work code quiz for this game on my website: http://www.codequizzes.com/

If you have any questions or comments on the application, please feel free to send me a pull request or an email.

If the tests are failing on your local machine because of deprecated methods or other RSpec errors, RSpec documentation can be found at rspec.info (recommended) or relishapp.com/rspec
