/**
 * EventEmitter
 *
 * This is a tiny event emitter meant to be used at several components that relay on each other to sync data in parallel.
 *
 * - In your class: this._emitterInstance = EventEmitter.createInstance(id) // unique id
 * - Listen to changes: this._emitterInstance.listen(function)
 * - Set new data: this._emitterInstance.set({...})
 * - Update new data: this._emitterInstance.update({...})
 * - Get new data: this._emitterInstance.get()
 * - Remove it like this: this._emitterInstance.remove()
 *
 * __EEE__ stands for __EUFEMIA_EVENT_EMITTER__
