CLINKAGE collide_t COLLIDE_Init	(	int	mpi_comm,
		const double *	gridStart,
		const double *	gridSize
	)

Create a new Collision grid.

This collective creation call must be made from all the threads of a TCHARM array.

Parameters:

	mpi_comm	is the MPI communicator, or 0 if not using MPI.
	gridSize	gives the size of one voxel, which should be several times larger than the size of the average object.
	gridStart	gives the origin of the voxel array--the corner of the voxel (0,0,0). For best performance, if possible you should align the voxel array so most objects lie in exactly one voxel.

CLINKAGE void COLLIDE_Boxes	(	collide_t	c,
		int	nBox,
		const double *	boxes
	)

Collide these boxes (boxes[0.

.6*nBox]). This is a collective call--all registered chunks should make this call. Unliked CollideClassed, below, no Collisions are ignored; or equivalently, every box lies in its own Collision class.

Parameters:

	nBoxes	number of independent objects to collide.
	boxes	an array of nBox 3d bounding boxes, stored as x-min, x-max, y-min, y-max, z-min, z-max.
