A very terrible first go at parsing and calculating mathamtical expressions.

This project evolved into the [calc_engine](https://gitea.copyrightcrusader.org/glm94/calc_engine) project which started as a striaght
C# to Python port, complete with the very horrible logic this repo shows off. The calc_engine later evolved into the [terrain_generator](https://gitea.copyrightcrusader.org/glm94/terrain_generator).

However, this project is offically abandoned and no longer active. Its only here as a archive of what I've done, and how much I learned since
writing this code. Which, to be frank, is very bad.
