Add a test framework

[d48]

I recommend adding some unit test framework and start creating assertions on the src files in the repo. Look into https://www.npmjs.com/package/tape or https://www.npmjs.com/package/mocha

Added Mocha, building tests as I go now.

Awesome. I would add to the .gitignore file:

node_modules/

It's common to not include this directory in the git repo so that it doesn't bloat the project. People can do an npm install to download the dependencies in the package.json file

Good point, thx!
