In order to reuse as much grob code as possible, I have been
seperating out things which are common between Grobs and Snobs into a
base object (Probs - property objects).  The first major hurdle I have
hit is that of interfaces.  I am having difficulty deciding whether
interfaces should be the domain of grobs only, whether there should be
a seperate set for snobs, or whether a single unified set should
suffice for both.  Would you have any insights into this question?
