Auto doc generation

Since we're all about making API docs easy, and since we have all the information we need, let's add a rake task or something similar that can automatically generate a boilerplate API doc for the given despecable controller actions.

First pass we can look through the code. But it'd be hella cool if we could define a new reader class that had different definitions of the integer, string, etc methods. We would need to load these ActionController subclasses carefully.

How do we distinguish between route and query params? Probably by parsing rake routes for symbols in the route.

On that note, parsing rake routes would be a great addition to this feature so we could auto-generate the full endpoints
