A Weyl equidistributed sequence sampler class optimized for a given number of dimensions (see http://extremelearning.com.au/unreasonable-effectiveness-of-quasirandom-sequences)
Weyl's equidistribution theorem says that the sequence of all multiples of an irrational number r is equidistributed modulo 1. This sampler uses such a generator for each dimension of a multi-dimensional sequence, where r is varied for each dimension.
