Fourier Series Animation (Square Wave)

Hi Guys :) Fixed fuzzy waveforms, was writing to integer screen coordinates. Added the third axis, in a 2D environment though.
My own programming, but thanks to meyavuz (YouTube), and Dom for help with this. iOS simulator can run it fine, but has a stutter hare and there when screen capturing.
