Detailed Description

Event system for the QB Actor Framework.

This file defines the event system used by the QB Actor Framework for communication between actors. It includes the base Event class and several specialized event types for different purposes, including quality of service levels, service events, and system events like kill and signal events.

Events are the primary means of communication between actors, ensuring isolation and thread safety in the actor system.
