  /**
   * A sample implementation of asynchronous API requests. This class provides
   * the ability to execute API methods and have the call return immediately,
   * without blocking the calling thread. This is necessary when accessing the
   * API in the UI thread, for instance. The request response is returned to 
   * the caller via a callback interface, which the developer must implement.
   *
   * This sample implementation simply spawns a new thread for each request,
   * and makes the API call immediately.  This may work in many applications,
   * but more sophisticated users may re-implement this behavior using a thread
   * pool, a network thread, a request queue, or other mechanism.  Advanced
   * functionality could be built, such as rate-limiting of requests, as per
   * a specific application's needs.
