@calvinfo @amillet89 Do we need to add anything to the test/style.json? I also wasn't sure what the go was with the Makefile, so I just added all the bits in that looked relevant :)
I think it's okay to keep client scripts like this all on one line--check out [this part of the jscs readme](https://github.com/jscs-dev/node-jscs#error-suppression)
