These headers have no associated C files, and are mainly used for utility logic. Having them in `/include` makes them more easily located, and more globally used. We are using "classic" header guards here over `#pragma once` for better support. Since `#pragma once` is defined by the compiler, rather than standard C. Why isn't it used across the project? I have no idea.
