    Like a ClassList, but shows classes hierarchical.

    If topClassHolders value is non-nil, only that classes hierarchy
    is shown.

    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.
