(provide (all-defined-out))

Submitting your Project: Choose a team name consisting of alphabetical characters. Put your file in a folder named <teamName>Project0, zip up the folder, and upload it to Canvas. Please make sure you name your folder correctly first, then zip it up, not the other way around. (You will have to resubmit if you don't do this.) If you submit early enough, let me know so I can test your code and give you a score. If you submit after the deadline please let me know right away so I can give you a grade.
