SCIH means Sun Compass In Hand.... it is an app which will provide a compass
heading based on the time of day and your ability to draw a line that
represents the direction away from the sun... It works both in the Northern
and Southern Hemispheres...
The code is well annotated and has some pretty heavy trig functions in it...
The app is based on the fact that at noon, the sun is directly south (in the
Northern Hemisphere), West at 6pm, North at 12 midnight, and east at 6am.
