This is a WIP, the idea is to copy VCR's behavior but with intercepted Rack requests.
- Specify which URL's must be intercepted/recorded
- Ensure complex bodies are safely stored in the YAML
- Keep some kind of application-wide list of accessed requests so tests can see what has been issued and with what parameters.
- Add query_string to the file name so we can have two different mocks for the same URL with different query strings.
- Whatever we find useful for it!
