Melanie Wehowski

This class can register handlers and dispatch named events.

It can register handlers objects and functions that will be called when a given event is triggered.

The class can also dispatch a given named event by calling all the functions of handler objects that were registered for that event.

This class is a conversion of npm event-state module to PHP.
