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.
