Used to generate the files.
This is inspired by jai's usage of the string_builder with #insert.
Its expected when using this library that Code ast will be serialized with the:
Builder::print() proc
The seralized content of the Code ast will be appended to Buffer within an empty line
prepared for a another definition or to add an empty newline to the end of the file.
Builder::write() should be called when all Code has been seralized for that file.
The #insert directive is thus represented by an #include of the generated file at your desired line
