/*
This source file defines the following class-based hierarchy:
root
subclass1
instance1
subclass2
instance2
subclass3
instance3
The root object imports the category "predicates", which defines one
public predicate, public/0, one protected predicate, protected/0, and
one private predicate, private/0.
All objects import the category "interface", which defines a predicate,
interface/0, for listing the object interface.
