/**
 * Default implementation of the OAuth protocol, version 2.0 (draft 11)
 *
 * This class is meant to be extended by concrete implementations of the API,
 * providing the endpoints and endpoint-http-verbs.
 *
 * If your Api adheres to the 2.0 (draft 11) protocol correctly, you just need to extend
 * this class and define the getters for your endpoints.
 *
 * If your Api does something a bit different, you can override the different
 * extractors or services, in order to fine-tune the process. Please read the
 * javadocs of the interfaces to get an idea of what to do.
