Testing

It'd be great to have some testing set up for this repo.

What would be really cool is if we could have CI for this repo that checks out the latest code from the Cookbook Template repo and builds / previews the template using the newly modified pythia.yml in this repo.

I don't know how to make that happen but it sounds like it should be possible?

This is similar to the testing issue for the cookbook-actions repo: ProjectPythia/cookbook-actions#6
