Got some new features working today. The code is a bit of a mess so I'll want to clean that up, but it's working so that's something.

The first thing is average rate of change through the range. Very easy calculation. The other thing that I'm thinking is percent breakdowns which nobody should be doing with roasting data, but I've had some thoughts on how to make those metrics less trash so I'll implement a couple variations on that and see what users think about it.
