sampling.lua
--- Sampling methods
-- Demonstrations of various methods for sampling from a pattern.
-- 1. pattern.sample generates white noise, it's fast and irreguarly distributed.
-- 2. Lloyd's algorithm when a specific number of uniform samples are desired.
-- 3. Mitchell's algorithm is a good (fast) approximation of (2).
-- 3. Poisson-disc when a minimum separation between samples is the only requirement.
