Tim Edwards 73314e30d7 Added some automatic handling of the "extract" section in the tech
file to generate a mask of all the types called out in the section
as being used for parasitic calculations (resistive and capacitive)
and device terminal types.  This is supplemented with a list of all
types that are specified in the "connect" and "contact" sections as
connecting to something other than themselves.  All remaining types
are considered non-electrical and removed from the list of types
that can be considered electrical nodes.  This works a bit better
than the existing method of using "resist <types> None" to specify
non-electrical types, as it is backwardly-compatible to older tech
files.  The upshot is that in the worst case, if a type needs to be
extracted as an electrical node but does not satisfy any of the
above criteria, then it should be added to the "resist" list, with
a resistance of 0 if necessary.
