## Macro Usage
For the most part macros are kept minimal with exception to `_Generic`...
*(I will be explaining this thing for the rest of this seciton along with gencpp c library's usage of it)*
The `_Generic` macro plays a key role in reducing direct need of the user to wrangle with mangled definition identifiers of 'templated' containers or for type coercion to map distinct data types to a common code path.
Because of its lack of use in many C11 libraries.. and, of those that do; they usually end up obfuscate it with excessive preprocessor abuse; Effort was put into minimizing how much of these macros are handled by the preprocessor vs gencpp itself.
