Relates from: #9

Things to test for:

• [ ] .wyd

• [ ] .whenfree
  • [ ] Command without the right structure fails

  • [ ] Mentioning busybee responds with a message with a winky face in it.
  • [ ] Mentioning a single user gets correct output

• [ ] .whobusy
  • [ ] Command without the right structure fails
    • [ ] No arguments

  • [ ] Test that UofT course codes get correctly split
  • [ ] Depending on #13, test that each school's course code gets split correctly

When using the .whenfree command with just myself as the argument, it gives the incorrect timing.

In the Winter 2022 timetable, on Wednesdays, I have a classes:

MAT157: 10:00 AM - 11:00 AM
MAT247: 11:00 AM - 1:00 PM
CSC209: 11:00 AM - 12:00 PM
PHL232: 3:00 PM - 4:00 PM
PHL232: 5:00 PM - 6:00 PM

When asking .whenfree though, I get output:

1 hour:  12:00 PM 02/02
2 hours: 12:00 PM 02/02
3 hours: 12:00 PM 02/02
4 hours: 06:00 PM 02/02
5 hours: 06:00 PM 02/02
6 hours: 06:00 PM 02/02
