I am really sorry for the absolute dumpster fire that this PR has been. I had a hard time getting adjusted to the project structure. I genuinely appreciate the feedback and help provided. This was maybe the first time I ever coded in C++ outside small university projects.

I'm pretty sure it is good to go now, but if any issues arise I will come back with the appropriate changes.
