WIP: Hypergrowth calculator

Adding some calculations to the Hypergrowth Calculator.

In plain English, what we want to get out of the calculator is:

	Long term %	This year %	This year $
ARR at the end of the year		100%?	???
Profit	100% - Total long term costs in %	100% - Total this year costs in %	This year ARR - this year total costs in $
Revenue growth		Growth rate %	??? ARR * Growth rate?
Cost of new ARR		Sum of Sales + Marketing %	Sum of Sales + Marketing $

This screenshot is of the current state of the calculator.
