Hopefully final correction to new extraction method. Now correctly
handles diodes or other devices with source/drain on planes other than the plane of the device type. This no longer requires that the non-connecting type be in any given terminal position. The device type boundary is surveyed for all types, connecting or overlapping, and at least one of each required type must be present.
