v.to.rast replaces NULL attribute values with 0, which fakes meaningful
values (Ksat 0 mm/hr, sand 0 percent, bulk density 0 g/cm3) for map units
without soil data such as urban land and water. Filter those records out
with a where clause so their cells stay NULL in 2D and sliced 3D outputs.
The notebook runs the manual workflow on the NC sample dataset with live
SSURGO data from Soil Data Access and saves the manual page figures. The
CMakeLists.txt enables g.extension installation with a CMake-built GRASS.
