 * @param parts
 * @desc RNG will be run under each of parts equal-sized partitions
 *       No partition will be run under twice before they've all been run under
 *       parts shouldn't be too large nor too small to maximize the chance for
 *       the RNG generated by Math.random() to be more evenly distributed
 *       Larger parts means more resources(mainly time) needed to run it
 * @default 10)
