Growth rate tester

[CamDavidsonPilon]

Users, and myself, would like a tool in the UI to change the KF settings, time series bounds, etc. to iterate on growth-rates from a recent OD time series. Some notes:

1. The feedback should be quick.

• Can we do this in JS?

2. Users should be able to select the time span (to remove crappy bounds)
3. Growth rate chart is exportable?
4. Ability to save to config?

Does it need to live in the app? Can we actually build a public service, generally: upload your CSV in X format, and hit go?
