Foam Extension Development Quick Start Guide

For OSX, tested on my computer on a monday. YMMV. I started without any node/etc installed.

I never got NVM to work for node versioning, so I defaulted to just using brew node:

	brew install node

And then install yarn and lerna globally:

Parameterize a solution space so all numbers are valid:
Solver coordinates are given as arctanh(radius), theta
Then minimize the inverse average distance (to maximize average distance).
