Full color support

This works great with my RGB laser projector.  There are options in output to support single or three color as well as TTL and Analog modes.  The examples/simple demo was updated to color cycle while spinning.  The simulator also shows the color, but probably not as well as green only worked before.

Some other random stuff too.  Invert program to invert the channels for my sound card correctoin amp.  Cal program showing a max size circle that cycles the colors for showing all colors and also setting channel levels on the correction amp.
