Detailed Description

Domain specific events.

This module defines the game's event mechanism. Events might be units moving or fighting, or when victory or defeat occurs. A scenario's configuration file will define actions to take when certain events occur. This module is responsible for making sure that when the events occur, the actions take place.

Game events have nothing to do with mouse movement, keyboard events, etc. These kinds of system events can be handled using namespace events
