simplify some method names and convert a couple functions to ES6 arrows
trying some ES6 template literals
IW: Start testing
IW: Rebuild the worker and shaders
IW: Exclude the node modules from es6ify
IW: Karma, route base/dist to dist

Not sure why this is the case, but Karma seems to append base to the
urls. This uses Karma's proxy system to fix that.
IW: TESTING, add chai
IW: Add a create method to Scene
IW: Update worker url for karma
IW: Sketch out tests
IW: Add more tests, use subject in tests
IW: Improve workflow with watch.sh
IW: Use es6 rest parameter syntax
