Setup CircleCI or similar.

[sircharleswatson]

We should set up Circle soon with at least eslint checking the code so the style is standard before merging things in to master

agreed, I never worked with Circle before but should not be much different than Semaphore or Codeship.

[sircharleswatson]

I've never used semaphore but I know Sam and Josh suggest Circle because it allows caching of things so it speeds up the build.

[benstr]

for sure, I want to give it a try!
