  scout_controller_action = "Controller/Sinatra/#{scout_sinatra_controller_name(@request)}"

#scout_sinatra_controller_name(request) ⇒ Object

Iterates through the app’s routes, returning the matched route that the request should be grouped under for the metric name.

If not found, “unknown” is returned. This prevents a metric explosion.

Nice to have: substitute the param pattern (([^/?#]+)) w/the named key (the key param of the block).
