PHP Event Mediator: Emit and listen to events using a mediator object

This package allows to emit and listen to events using a mediator object.

It provides a class that implements the mediator design pattern to perform operations with objects of classes that abstract emitted events and listeners that process those events when they happened.

Currently it can add a listener to a given event by name, or add a subscriber, get the listeners a given event name, check if a given event name has listeners, remove a listener to a given event, remove a subscriber and trigger a event.
