/**
 * HTTP request initializer.
 *
 * 
 * For example, this might be used to disable request timeouts:
 * 
 *
 *   public class DisableTimeout implements HttpRequestInitializer {
    public void initialize(HttpRequest request) {
      request.connectTimeout = request.readTimeout = 0;
    }
  }
 * 
 *
 * 
 * Sample usage with a request factory:
 * 
 *
 *   public static HttpRequestFactory createRequestFactory(HttpTransport transport) {
    return transport.createRequestFactory(new DisableTimeout());
  }
 * 
 *
 * 
 * If you have a custom request initializer, use this more complex example:
 * 
 *
 *   public static HttpRequestFactory createRequestFactory(HttpTransport transport) {
    final DisableTimeout disableTimeout = new DisableTimeout();
    return transport.createRequestFactory(new HttpRequestInitializer() {
      public void initialize(HttpRequest request) {
        disableTimeout.initialize(request);
      }
    });
  }
 *
