Clarify how route variables work. (gorilla#151)

(this confused the heck out of me while trying to use Gorilla) * Changed `request` to be just `r`, like the other handlers. * Created complete wrapper function instead of just 2 lines.

 The names are used to create a map of route variables which can be retrieved calling `mux.Vars()`:
 
 ```go
-vars := mux.Vars(request)
-category := vars["category"]
 func ArticlesCategoryHandler(w http.ResponseWriter, r *http.Request) {
 	vars := mux.Vars(r)
 	w.Header().Set("Content-Type", "application/json; charset=UTF-8")
 	w.WriteHeader(http.StatusOK)
 	fmt.Fprintf(w, "Category: %v\n", vars["category"])
 }
 ```
 
 And this is all you need to know about the basic usage. More advanced options are explained below.
