When generating a sequence of random numbers you will notice that it tends to clump. However, sometimes you want a bunch of samples that are better distributed. A binary random jittered (BRJ) sample is a series of random numbers which are relatively evenly distributed, similar to random_sobol().

The seed allows you to generate different sequences. If it is a floating point seed, note very small differences will select very different sequences.

The offset is which entry in the sequence to extract. This should be an integer sequence, like ptnum, in order for the distribution property to work.

Each number is in the [0..1) range.
