    5  *  A is shared between two WorldEntity's CollisionHandles if both are subscribed to this event. In this case only one
     5 *  Is shared between two WorldEntity's CollisionHandles if both are subscribed to this event. In this case only one

    77 *  to signal that it's already cared about and should be ignored.
     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.

     5 *  A collision event represents a collision of two bouning boxes. Every CollisionEvent belongs to a Collision object that
     6 *  represents the collision of two WorldEntities.
     7 *
     8 *  There are different types of collisions: obb collisions and bsp collisions. Both collision types use different techniques
     9 *  to represent collisions. This is why this class saves bounding boxes from the OBB as well as the planes from BSP.
