Spend no more than 2 hours building a Rails (or Sinatra) app that allows the player to play a game of tic-tac-toe. This should be for 2 human players, so no AI is needed (unless you wanted to make this harder for yourself).

Don't worry about views, in fact, we'd specifically like for it to render a readable plain text response in the response body. We should be able to play by just CURLing api. Moves can be made by postings the player (x or o) to positions like 0,2.

Please post the project to Github as you work.
