Code Structure

In order to stick as close to the API, I used the subsonic API documentation for organise the code.

Each method in the subsonic rest API which return a subsonic-response is represented by a class which inherit from the abstract class Response where T is the class type.
Each class in the dll have a Request method which take or not parameter according to the API.
This allow us to create wrappers without parsing or configuring anything.
I used XmlSerializer to parse and create object without parsing.
