Add a function to get course history

[William-Chapin]

Add a way to view your course history, I tried adding it myself but I kind-of suck at coding, and I just kept getting critical errors.

if you check my account I made something that can do this, it takes your credentials for logging in, and then stores your course history as a .json file (This is very beta and it cannot do anything besides this one function as of now)
