//  Perlin.swift
//  Created by Matthew Reagan on 8/7/18.
//
//  Quick implementation of the the classic Perlin noise
//  generation function, useful for creating organic textures
//  or terrain. Perlin noise can also be easily generated with
//  Apple's GameplayKit framework, this code is mostly for
//  experimentation purposes. (Disclaimer: This code is not
//  optimized, nor particularly elegant, but it can be used as
//  a jumping off point for writing custom noise functions.)
