Alas, that's backwards from the main intent of paramsets.
Recall that BSIM3/4 have hundreds of (model) parameters,
and we want to restrict instances such that they can only
specify l and w -- that way the other (hundreds - 2)
can share storage. It doesn't make sense to have to
disinherit the (hundreds - 2) parameters we don't want.
