[SYSTEMML-1991] Implementation of Sobol quasi random sequence generator

[j143-zz]

Sobol Quasi Random Sequence generator
This outputs a matrix, of points of shape NxD. where N - no.of points, D - no. of dimensions.

How this works?

1. This script contains precomputed direction numbers for initialization.
2. Using these direction numbers further the direction vectors calculated.

Example sequence: N = 4, D =3

0.0    0.0    0.0
0.5    0.5    0.5
0.75   0.25   0.25
0.25   0.75   0.75
