Its a cookbook class that we use to abstract cookbooks and their
dependencies. The key method to look at is dependency_hash which creates
a hash based on the dependencies of the cookbook.

We do not explicitly do a reverse dependency lookup but we can use this
hash to infer a change in dependencies from a change in any cookbook in
an environment. So the flow is:

1. I change cookbook A and it gets sent to the chef server and indexed
