Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name) ⇒ Object

This literally passes to the JSON response that we get. This means that if the server returns a string for a key, you will get that. If it returns a hash with more info, so will we. Hey, this is 2.0.0 baby. We’re allowed to play hardball.
