 - **DEPRECATE** the `app.StaticServe`, use `app.StaticWeb` which does the same thing but better or `iris/app.StaticHandler` which gives you more options to work on.
 - add some debug messages for route registrations, to be aligned with the mvc debug messages.
 - improve the https://iris-go.com/v8/recipe  -- now you can see other files like assets as well -- lexical order of categories instead of "level".

 - [ ] give the ability to customize the mvc path-method-and path parameters mapping,
 - [ ] make a github bot which will post the monthly usage and even earnings statistics in a public github markdown file, hope that users will love that type of transparency we will introduce here.
