[5039]2 * @file collision.h
[10013]3 *  Definition of a collision relation of two WorldEntities
[8124]4 *
[10013]5 *  Is shared between two WorldEntity's CollisionHandles if both are subscribed to this event. In this case only one
[8124]6 *  of the two CollisionHandles will calculate the CollisionReaction and the bDispatched flag will be set afterwards
7 *  to signal that it's already cared about and should be ignored.
[10013]8 *
9 *  The collisions itself are saved in this container (CollisionEvent). Since there can be multiple collision events
10 *  for one collision. Imagine: two objects are intersecting (this throws a Collision): many collision boxes will fire
11 *  each of this boxes will "create" a CollisionEvent.
