While we do enforce ruby 2.0.0 for production, enforcing a specific ruby version can make it difficult for people to contribute. Consider if someone doesn't have ruby 2 installed on their system, or they have a slightly older point release. What about our boots who all have 1.9.3 on their machines and the Dev Bootcamp machines?

Do we really want to discourage their contributions?

Our (hopefully soon to be integrated) [travis.yml](https://github.com/Devbootcamp/mentor-pairing/blob/fd5e379e1830130ffe90838da9ea8fc2e5edc920/.travis.yml) specifically runs against both 1.9.3 and 2.0.0; which gives us some amount of confidence that all pull requests will work with both versions going forward.
