Detailed Description

template<class T>
class PerlinNoise< T >

Generates Perlin noise - a type of gradient noise with natural-looking characteristics.

Perlin noise is widely used in procedural generation for creating textures, terrain, and other organic-looking random variations. It produces smooth, coherent noise with controllable frequency and amplitude.

Based on the reference implementation by Ken Perlin. See: http://mrl.nyu.edu/~perlin/paper445.pdf
