Detailed Description

Interface for the JContainer class

                        The JContainer Class

Class for a collection of objects stored in a JList.

By calling InstallCollection in the constructors and copy constructors,
derived classes need not worry about keeping JCollection::itsItemCount
up to date.  This class does it automatically by listening to Broadcast
from the specified JList.

Implementation notes:

We store a JCollection* only to avoid making this class a template.
We should actually store an JList*.  But instantiating templates
is such a pain, and, in this case, is conceptually unnecessary.
