/********************** collideClient *****************
A place for the assembled Collision lists to go.
Each voxel calls this "Collisions" method with their 
lists of Collisions.  Because there can be many voxels per 
processor, the canonical implementation does some kind 
of reduction over the voxels array--this way you know
when all voxels have reported their Collisions.

If you just want the Collisions collected onto one processor, 
use the serialCollisionClient interface below.
