This program will create a shaded-relief cube from a topographic cube. It uses the sun angle (azimuth)
as well as the solar elevation (zenith) to compute the correct shading on the output cube.
Changed user parameter names and now read pixel resolution
from labels.

Reversed slopes to be correct. Changed azimuth to be 0 degrees is 12
o'clock rotating clockwise. Updated documentation to match.

Abstracted out the hillshade algorithm (the algorithm that computes the resulting values from
this program) into it's own class. This program's code has changed to utilize the new class,
but the functionality should be unchanged. References #1232.
The pixel resolution of the image. This parameter will default to
the value from the labels or may be used to increase or decrease the
apparent steepness. If no mapping group exists, the user must enter a
pixel resolution. Greater than the image's pixel resolution will level
and smooth, and less than will make steep and sharpen.
