Detailed Description

The GravityExtern is a wrapper of the GravityAffector, adding the functionality of a MovableObject. The GravityExtern can be attached to another SceneNode than the one where the ParticleSystem at which the GravityExtern is registered, is attached. This makes it possible to affect the particles in the Particle System, while both SceneNodes moves different from each other. This approach makes it possible to simulate something like a helicopter (SceneNode to which the GravityExtern is attached) that flies over a certain area and moves the leaves on the ground (Particle System attached to another SceneNode).
