now i could. it's in a command plugin I have added to gnucap-custom. the
cmk command can be used to order the nodes in (individual) subckt models
or in the top level circuit. it does not require changes in gnucap.

however, i had to break into NODE_MAP, to access the private map.
please consider a public

void NODE_MAP::permute(int* p);

in the official header. it permutes the user numbers, and plays nicely
with the rest of it.

i'd be happy to know how you intend to address this. it's more important
to me than speed, right now.
