 This is extension of [MessagePortDispatcher](https://github.com/burdiuz/js-messageport-event-dispatcher) to work with Dedicated and Shared Workers. It makes possible two-way communication with Workers using custom events. So, instead of using `postMessage()` and catching `message` event all the time, you are free to send any type of events to and from worker.
