    Like a HierarchicalClassList, but shows class inheritance.
    For non-meta classes, this is the same as would be shown in
    the hierarchy list;
    For metaclasses, the tree is extented through the class-behavior
    hierarchy.

    embeddable application displaying the classes as listed by
    the inputGenerator.
    Provides an outputGenerator, which enumerates the classes and
    their protocols (method-categories) in the selected classes.
