Wanted to make parser implementation easier to sift through, so I emphasized alphabetical order more.
Since I couldn't just strip whitespace from typenames I decided to make the parse_type more aware of the typename's components if it was a function signature.
This ofc lead to the dark & damp hell that is parsing typenames.
Also made initial implementation to support parsing decltype within a typename signature..
The test failure for the singleheader is still a thing, these changes have not addressed that.
Also now doing comment serialization on def_comment directly as parse_comment doesn't need it.
Essentially comment ast types serialize the same way s untyped and execution ASTs
This isn't the last step though everything in the main project directory that isn't md files needs to be generated only.
Can't do that till testing is robust enough...
