Thanks for the Network Expression term. It is exactly what I was
looking for. I just haven't looked enough at the Computational Biology
work recently--it's just over my horizon and probably shouldn't be.
BTW, I know plus as positive-closure to distinguish it from
Kleene-closure, but prefer the terms star and plus as they are simpler
and shorter and in context clear. I don't know of anyone who says
x-Kleene-closure, for "x*", but anyone working on regular expresions
immediately knows what "dot-star" means, although many quible over
whether it includes "newline" characters of not. :-)
