Implemented a lot of stuff for javac, but we ran into 2 major issues still to be implemented:

1. The visit mode of a lombok handler (does not trigger off of annotations, instead sees every field, method, type, and statement), needs to be coded,
2. triggering off of annotations via APT's annotation handling system skips method-local classes. We'll need to recode this via an AST visitor like we need for issue #1

Other than that, triggering off of annotations works swimmingly!
