- how to incorporate the metadata processor to start with
- create a hook to programmatically configure the test
- create a plugin processor
- directory
- jar
- hooks for loading

- I could make an annotation that marked another class as its plugin discoverer, I could just add it to
  the component descriptor and when it's loaded we can add the discoverer, that would be simpler. I could
