sorry -- meant to respond there...

Nick - that is a perfectly good point. Obviously a 2D representation is
ambiguous with regard to conformation. So that's a limitation. I've put in
some minimal checks, but it is still going to be an issue.
Particularly with cyclohexane conformations you might get odd results as you
mention.
