Rapid React: Tests

[TheAnnalyst]

Rapid React will need unit tests for:

• [x] storage
• [x] ranking point tallying
• [x] point tallying
  • [x] cargo shots
  • [x] climbing
  • [x] misc (e.g. crossing start line in auto)
• [ ] input validation (do this server-side on the scouting website)

I'm planning to take on testing as my immediate next step, but if anyone else wants to help out you're welcome to :)
