Preparing to implement ADT for csv functions.

Browse Source 
I'm rewritting it the way I'd like to learn it.
- I want to use csv parsing heavily with the library so I'm just going to add it to the scanner.

- Globaly memory allocator moved to regular gen header/source as its something really just made for the library.
- Some small refactors to macros
- The parser was updated to support tokenizing preprocessor directives.
  - The purpose is based off intuition that it will be required for the scanner.
