Add logging, statistics, and automation

[stacksjb]

Would like to add logging, statistics, and automation

For example, "For Course x, there are 15 assignments in canvas, 12 submitted, 4 unsubmitted, 2 null, 1 locked", with a summary printed at the end. IThis would also be extrememly helpful in identifying bugs)

Adding logging to file and automation would help so that I can add the ability to automatically run it on schedule.
