Title: Implemented Perlin noise

I ported perlin noise exactly from [PApplet.java](https://github.com/processing/processing/blob/master/core/src/processing/core/PApplet.java). As far as I can tell it works as expected. My unit test is nothing great, just checks to make sure we get a number between 0 and 1. Also, seeding has not been implemented yet. Finally, I'm not 100% sure I incorporated the new noise.js file correctly.

I'm more than happy for someone to look this over and tell me I'm doing things wrong.
