// ZipfSetBits sets bits randomly and deterministically based on a seed, according to the Zipf distribution
// ZipfSetBits sets random bits according to the Zipf-Mandelbrot distribution.
// This distribution accepts two parameters for both bitmaps and profiles:
// Exponent in (1, inf), default 1.001 - "sharpness" of the distribution.
// Ratio in (0, 1), default 0.25 - maximum variation of the distribution (the relative probability of the least likely ID to the most likely ID)
//
// It also uses PermutationGenerator to permute IDs randomly.
