Ben Ceron / Mbed 2 deprecated NeoPixel-DemoBuffer

Demo of NeoPixels using buffer/array of pixels method.

Dependencies:   PixelArrayBuffer mbed

Edit of Jacob Bramley's original NeoPixel Demo code. https://developer.mbed.org/users/JacobBramley/code/NeoPixel-Demo/ This code simply demos the buffer/array of pixels method in updating the NeoPixel chain. The original version of this code used the generator method.
