  Log Message:
  -----------
  Add DerivativeWriter

The derivative writer produces a GeoTIFF of one of the following primary
topographic attributes.

* Slope D8 (default)
* Slope FD
* Aspect D8
* Aspect FD
* Contour curvature
* Profile curvature
* Tangential curvature
* Total curvature
* Hillshade
* Catchment area

Surface derivatives are computed using the max Z value at a given grid
size.
