Cascade class

A helper that calls several handlers in sequence and returns the first acceptable response.

By default, a response is considered acceptable if it has a status other than 404 or 405; other statuses indicate that the handler understood the request.

If all handlers return unacceptable responses, the final response will be returned.

 var handler = new Cascade()
     .add(webSocketHandler)
     .add(staticFileHandler)
     .add(application)
     .handler;
