Uses the distance function from the MATLAB Mapping Toolbox to calculate the arc distance to the sub-solar location. Includes checkSizes function from my general function library.
EarthEphemeris - Returns the solar declination, Earth-Sun radius vector (distance in astronomical units), solar longitude, and optionally the equation of time.
sunang - Returns cosine of sun angle, its azimuth (0 south, + east), and airmass (path length accounting for Earth curvature). Optionally accounts for refraction.
sunRiseSet - Times of sunrise and sunset.
sunslope - Cosine of illumination angle on slope

1.2.2

MATLAB functions calculate azimuths clockwise from North. My convention has been to use counter-clockwise from south, positive east, negative west. I added a function to let the user choose which convention to use.

removed call to today(), I didn't realize it was in the Financial Toolbox, thanks to Christie for reminder to use clock() instead. Also fixed a glitch in PlotSolarPath.
