  By default, `setup` will remove all files from the game folder.  You do not need to include a setup method if you don't want an initial git repository (if you are testing `git init` or only checking an answer.)
-

  You can call `repo.init` to initialize an empty repository.
 
  All methods called on `repo` are sent to the [grit gem](https://github.com/mojombo/grit) if the method does not exist, and you can use that for most git related commands (`repo.add`, `repo.commit`, etc.)
