[x3d-public] Procedural collectors, Chaotic collectors

[GPU Group]

One idea is to add collectors to the physics based emitter scenarios.
The physics changes the particle's position based on physics formulas,
on each iteration. A collector could have 'influence' on the position,
based on
a) time since emitting, with the greater time, the more influence
position = lerp(delta_time, physics_position, collector_position)
so that as time goes on, the collector position dominates until the
particle is at the collector
b) nearness to a collector - with multiple collectors in the scene, it
would be nice if a particle would go to the closest collector.
collector = closest(collector_list,particle_position)
position = lerp(delta_time, physics_position, collector_position)
