    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.
