Challenge #9: Analytics Ranking

[MGerber]

Attaching my solution- not sure this is the cleanest approach so will be reviewing others' ideas now to see what they came up with. That's been my favorite part so far about the weekly challenges. Seeing how others are approaching the same challenge is giving me many more ideas and exposing me to new tools I hadn't thought of using before.
