Add CircleCI to repository

[lukebaker]

@bstewart, I added some CircleCI setup to the repository to ensure that the site builds with every commit. However, as the repository owner, I'll need you to actually enable / install CircleCI for this repository. CircleCI will run these builds for free for public repositories, so there's no need for more than their free plan.

Here are the steps:

1. Visit the CircleCI signup page
2. Next to the "Sign up with GitHub" button click the down arrow and then "Public Repos Only" [screenshot]
3. Click "Authorize circleci" [screenshot]
4. From the CircleCI dashboard, click "Add Projects".
5. Find "princeton_methods_camp" and click "Set Up Project"
6. Click "Start Building"

I think that's all. Let me know if you have any questions. Thanks!
