Style enforcement and CI

I'd recommend that you guys setup a style guide and lean on something like https://houndci.com for enforcing style, as I can already see in #14 inconsistencies in spacing, `"` and `'` etc

I'd also recommend using like https://travis-ci.org for CI. Both of these services are free for open source.

Lastly, http://codeclimate.com/ is amazing and is also free for open source.
