- There are several theme template "renderers" all over the codebase
- Some are in apps, and were called "controllers"
- One is in error handling
- All of them now have comments marking out how they share logic/steps
- Other comments describe routes & controllers where they live
refs #9192
- Instead of `setupRoutes` function in apps that gets passed a router, there is now a registerRouter function as part of the proxy
- Moved towards a route service, which will know about all routes
- Using classes to abstract away shared behaviour
Notes:
- changing the app proxy didn't result in a test failure!
- structure of route service is totally new and may change a lot yet
