Subject: [PATCH] Add Mount method to Route.

With Mount method, we can simplify subrouter with tidy code.

```
todos := r.PathPrefix("/todos").Subrouter()
todosResource{}.SubrouterFunc(todos)
```

```
r.Mount("/todos", todosResource{}.SubrouterFunc)
```


```
type todosResource struct{}

func (rs todosResource) SubrouterFunc(r *mux.Router) {
	r.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		_, _ = fmt.Fprintln(w, "entry [/todos/].")
	})
	r.HandleFunc("/list", func(w http.ResponseWriter, r *http.Request) {
		_, _ = fmt.Fprintln(w, "entry [/todos/list].")
	})
}
```
