Ed_ c5afede7b5 Reorganization of files, refactors, doc updates (WIP)
Removing the gen. namespace from the files for components, dependencies, and file_processors.
They are only necessary if the include directory is transparent, and in my case those are not.

Made a docs directory. I'm offloading information from the main readme to there along with additional informationn I end up elaborating on down the line.
Enum tables were moved to their own directory (project/enums).

Library will not compile for now. Major refactor occuring with parsing related components.
