Model evaluation

[maximk27]

Ways to measure how well the model is performing:
Perplexity
Human Eval (optional)

This is on feat/evaluation:
https://github.com/MichiganDataScienceTeam/F24-mini-copilot/tree/feat/evaluation

I will be gone this weekend, just opening this issue so anyone can get started

Perplexity is done, human eval remains if anyone is interested
