+ ** George Marsaglia invented the RNG-Kiss-family in the early 90's.
+ ** This is a specific version that Heinz van Saanen derived and
+ ** tested from some public domain code by Bob Jenkins:
+ **
+ ** Quite platform independent
+ ** Passes ALL dieharder tests! Here *nix sys-rand() e.g. fails miserably:-)
+ ** ~12 times faster than my *nix sys-rand()
+ ** ~4 times faster than SSE2-version of Mersenne twister
+ ** Average cycle length: ~2^126
+ ** 64 bit seed
+ ** Return doubles with a full 53 bit mantissa
+ ** Thread safe
