Function that initializes (or `seeds') the random number generator.
- Parameters:
-
seed | : value of seed to be used |
From GSL manual: If the generator is seeded with the same value of s on two different runs, the same stream of random numbers will be generated by successive calls to the routines below. If different values of s >= 1 are supplied, then the generated streams of random numbers should be completely different. If the seed s is zero then the standard seed from the original implementation is used instead.
