Functions
Value	nk::stats::randsample (::nk::ops::RngContext &rng, int N, int K, bool with_replacement, const Value &weights, std::pmr::memory_resource *mr=nullptr)
	Sample integers from 1..N (r = randsample(N, K, replacement, weights)).
Value	nk::stats::datasample (::nk::ops::RngContext &rng, const Value &X, int K, int dim, bool with_replacement, const Value &weights, std::pmr::memory_resource *mr=nullptr)
	Sample rows / columns of an array (Y = datasample(X, K, dim, replacement, weights)).
Value	nk::stats::combnk (int N, int K, std::pmr::memory_resource *mr=nullptr)
	Enumerate K-combinations of 1..N (C = combnk(N, K)).
Value	nk::stats::combnk (Span< const double > v, int K, std::pmr::memory_resource *mr=nullptr)
	Enumerate K-combinations of an arbitrary vector (C = combnk(v, K)).
