Added a colorsmith file

Well this isn't really a colorsmith specific file (any of the files in this
repo work as input to colorsmith). This is just an example of colorsmith code.
Remember you need a raspberry pi with a PiGlow to view this. COLORS ABOUND :D
Removed the comment from the colorsmith file

That comment will affect the command stream and thus the leds of the PiGlow
