Handler bubbling

[jirenius]

Issue

In case a res.Handler does not contain a handler method for a given request, it should bubble up to the next best res.Handler match.

Example

s := res.Service("test")
s.Handle("model",
   res.GetModel(func(r res.ModelRequest) {
      r.Model(json.RawMessage(`{"foo":"bar"}`)
   }),
)
s.Handle(">", res.Access(res.AccessGranted))

An access request, access.test.model, should be handled by the handler for the wildcard ">" as the "model" handler has does not have an access handler method.

I would really like to help you add this feature. I would like to know if the goal is to modify the add() method of the Mux type?
