Travis ci

Could you enable [Travis-CI](https://travis-ci.org/) for this project? Once that's done, I can add another commit into this PR with the badge for the README.

This will trigger a build on Travis-CI which get this PR passing before merging.  Going forward, I want all tests passing before merges happen to avoid hotfixes.  This will be useful for others as well to know if the code is in a stable or unstable state.
