One final note-- I tried short-cutting the implementation of the GoF
Composite pattern by simply slapping a Children property onto my Apples and
Oranges classes. I ended up needing a lot of tangled code to keep straight
whether I was dealing with a folder or an item. So, I've gone back and
refactored to implement the pattern as suggested by the GoF in both classes.

The lesson I learned: The GoF patterns are held in high esteem for a reason.
They really are time-tested solutions to recurring problems. Short-cutting
them can easily lead to more refactoring down the road.
