When we finally get commons-functor generified, I'm going to create an
IModel implementation that takes a UnaryFunction and wraps another
IModel. This would probably be a read-only model, though (unless you
supply the UnaryFunction's inverse also I guess). This would be
reusable so that you can swap in any function you want
(UpperCaseFunction, etc.). Another option would be to use the Commons
Collections Transformer interface (as soon as it's generified), since
there are probably a lot of existing implementations of those flying
around (we use them a LOT on our project).
