planck_rng

The derived type planck_rng is used by the Random Number Generation routines rand_init, rand_uni, rand_gauss to describe fully the current RNG sequence.
Most users do not need to know about the planck_rng definition. It may be useful for those wanting to take a snapshot of the RNG sequence they are using (by eg, dumping the latest values of planck_rng structure on disk) so that the same sequence can be resumed later on from that same point.

gset	DP	internal variable for Gaussian RNG
empty	LGT	flag used by Gaussian RNG
