This is a plugin for chai to simplify the testing of EventEmitter.
EventEmitters can be testing using spies, but they are rather heavyweight for most usecases:
var spy = sinon eeeetohavebeen spyeetohavebeen
chai-eventemitter replaces this with something much more digestable:
node.js / io.js
var chai = chai
