Title: Notes on how to use martini with other frameworks, in particular Google App Engine

I'm sure there are other examples of integration, I just needed it for GAE and it turned out to be trivially adaptable, because you guys built nicely on top of the Go API, good job!

You mention multiple time that Martini is fully compatible with http.HandlerFunc "interface". But that only mentions downstream compatibility apiwise, i.e. fit any function matching the http.HandlerFunc signature.
