- Removed the BCCNoise functions.
- Rewrote the webgl-noise functions to use more modern and simpler way to generate gradients.
- Function renaming: snoise -> SimplexNoise, cnoise -> ClassicNoise, pnoise -> PeriodicNoise
- Added include guards. Now you can use these shaders without conflicts.
- Changed the normalization coefficients. Now these noise functions return values roughly fit in [-1, +1].
