Figure out a good standard for how to use the HTTP response codes in a 'truly RESTful' (Now called 'Hypermedia API' apparently) way.

Summary

• HTTP Methods (Verbs)
  • Spec: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
  • OPTIONS: Display which HTTP methods can be called on a resource.
  • GET: Just get a resource.
  • PUT: Update a resource
• PATCH: Partial update of a resource (not universally supported)
