 The overall goal for this project is to utilize the efficiency of Rust to create a Chess AI matching the speed of modern chess engines.
 For the engine, the majority of the code is a direct port of Stockfish's C++ code. See [their website](https://stockfishchess.org/) for
 more information about the engine. As such, the credit for all of the advanced algorithms used for searching, evaluation,
-and many others, go directly to the maintainers and authors of Stockfish. This project is simply for speed comparisons
