Rewrite to be a better API

[KAllan357]

This might be a large task, but we are missing a few key things:

• adequate testing
• a consistent style
• some randomness between sending / receiving XML or JSON.

I was sorta thinking this might be an interesting place to do some metaprogramming (similar to Ridley) and maybe some experimentation with Celluloid (maybe we don't need to worry about concurrency, thought)

[josephholsten]

certain operations have to happen in order, which would muck with naive concurrency.

I'd definitely support moving the HTTP calls to faraday though.
