%description
Generates random and quasi-random space-filling sequences. Supports the
following sequences: 'Halton', 'Sobol', 'Owen'-scrambled 'Sobol',
'Owen'-scrambled 'Sobol' with errors distributed as blue noise,
progressive jittered, progressive multi-jittered ('PMJ'), 'PMJ' with blue
noise, 'PMJ02', and 'PMJ02' with blue noise. Includes a 'C++' 'API'.

two-dimensional projections" (2012) <doi:10.1137/070709359> S. Joe and F.
