Static Public Member Functions
static Long	NextID ()
	Returns the next particle ID for this processor. Particle IDs start at 1 and are never reused. The pair, consisting of the ID and the CPU on which the particle is "born", is a globally unique identifier for a particle. The maximum of this value across all processors must be checkpointed and then restored on restart so that we don't reuse particle IDs.

static Long	UnprotectedNextID ()
	This version can only be used inside omp critical.

static void	NextID (Long nextid)
	Reset on restart.
