Minor refactoring and cleanup.
Pushes apparent repeated functionality to util and adds comments. Removed a few debuggery TODOs.
Documentation of wrapping code.
Pushed parse_transform to aspecterl.
Previous execution of injector called extractor anyway, so I merged the two under the primary module. This commit also cleans up and modernizes the documentation of the modules so that doc generation is cleaner.
Support for edoc.
Fixes for parse_transform relocation.
