// Name: msglm
// Date: Nov-14th-2022
// Program Name: parse CSV
// Description: parses a character-seperated value sequence. Not very robust.

//This program is a bit less barebones and cool than I wanted, that's because, while working on the original project, I noticed my GPU fan had gone out
//and that I have been risking overheating my computer. I promptly ceased using my computer and repaired the device. This was about 50% of the way through
//completing the program. By the time I had the thing fixed, I was working on borrowed time and opted to scrap the original project for something more simple.
//
//The project in question was a small, tile-based territorial control game where AI would battle it out for control over the whole board. I had a good portion of it done, but
//still a lot more to get done. Once I got my GPU back in, I saw how much was necessary, and ditched the whole project because of time constraints.
//
//Lesson learned: never do cool things when under a deadline.
