Random particle offset in tyCache

[Laserschwert]

I'm currently planning on adding some geometry options to the tyCache object...I like the "# copies per particle w/random offset" idea

I think it would make sense to allow filtering of which particles of a tyCache would be affected by this. So for example when you have a cache consisting of both debris and dust particles, and only want to multiply the dust particles.

By the way, if I understand the doc's description of the Resample node correctly, that one would work even better for upping the resolution of a sim. Would that be too costly for tyCache playback?
