a lot of binning models.
This is a hack and needs testing!
inpcom.c: If an x line, add w and l to the netlist card,
if available.
subckt.c: select a suitable model bin, discard the rest
for each subcircuit, depending on w and l from above.
inpgmod.c: less restrictive equal for real numbers,
allow both min and max boundaries (problem of equating
real numbers), when the selected device has w or l on
the boundary between two model bins.
