/**
*
* The Event Aggregator pattern channels events from multiple objects
* into a single object to simplify registration for clients.
* A system with lots of objects can lead to complexities when a client wants to subscribe
* to events. The client has to find and register for each object individually, if each
* object has multiple events then each event requires a separate subscription.
* <p>
* An Event Aggregator acts as a single source of events for many objects. It registers
* for all the events of the many objects allowing clients to register with just the aggregator.
* <p>
* In the example {@link LordBaelish}, {@link LordVarys} and {@link Scout} deliver events to
* {@link KingsHand}. {@link KingsHand}, the event aggregator, then delivers the events
