to be noted that this attribute does not work correctly for nParticles in maya 2010...grrrr

Now in maya2011 they come clean in the docs....

The collisionGeometryIndex output attribute is not supported for nParticle collision events in Maya 2011.

Oh dear...now no easy real way to manage hirez splahes from a lorez sph particle sim....shame
