That's really a change that doesn't change anything.

But now I see remember the MODEL_CARD is needed, and recall the 
intent .....

The MODEL HIERARCHY is still unnecessary baggage.  The model 
expansion mechanism is based on cloning objects, so having two 
is bad.

So ...  MODEL_CARD should become "final" in the sense of not 
inheriting from it.  The "is-a" relationship should change to a 
"has-a" relationship.

The MODEL_CARD should become simply an enclosure to block its 
contents from evaluation.  All models (subckt masters, 
paramsets, spice .model, etc) get a MODEL_CARD, with whatever to 
clone attached at _component_proto.  Having it one step away 
will block subckt masters and the like from being evaluated.

This was the original intent .. it's coming back.


I am swamped now ... preparing for a conference next week.  I 
expect to have more time to look at it after the conference.
