Tiny, ES2015 EventEmitter Class

Installation: npm install es2015-event-emitter

Usage:

let EventEmitter = require('es2015-event-emitter');

class MyClass extends EventEmitter {}
let mc = new MyClass();

mc.listenTo(someObj, 'change', () => {});
someObj.trigger('change');

Run tests:

npm test

Notes:

This currently only works with the --harmony flag passed to Node. A build step will be added shortly to make it work in ES5 environments, even though they already have plenty of EventEmitter implementations.
