Made a correction to extHierSubstrate, which was checking for 

substrate shielding types in a subcell inside the interaction area
only.  Since the interaction area is clipped by the "cookie cutter"
extraction areas, it could completely miss the shielding.  As
revised, any shielding under a subcell will effectively shield the
entire subcell.  This could be improved by warning if the subcell
has substrate connections outside of the shield area (as that is
not extractable), but that requires additional processing.
