/**
 * This class provides an abstract {@link RequestHandler} implementation with reasonable defaults for everything but
 * {@link #handleRequest(Request, ResponseHandler)}.
 *
 * A very simple hello world handler could be implemented like this:
 *  * class HelloWorldHandler extends AbstractRequestHandler {
 *
 *     @Override
 *     public ContentChannel handleRequest(Request request, ResponseHandler handler) {
 *         ContentWriter writer = ResponseDispatch.newInstance(Response.Status.OK).connectWriter(handler);
 *         try {
 *             writer.write("Hello World!");
 *         } finally {
 *             writer.close();
 *         }
 *         return null;
 *     }
 * }
 *
