Models, Controllers, Views, Routes recipes still mentioned in tutorial

[vfonic]

I was following the tutorial here: https://github.com/RailsApps/rails_apps_composer/wiki/tutorial-rails-apps-composer#models-controllers-views-routes

And found out that these recipes no longer exist as of this commit: https://github.com/RailsApps/rails_apps_composer/commit/5fcf96caf1999e75368236e62f7096597304f205

It would be good to update the documentation. Thanks!
