/*  [Description]

    The class SfxShell is the base class for all classes, which provide
    the functionality of the form <Slot>s.

    Each instance has a reference to an interface description, which is
    obtainable through <SfxShell::GetInterface()const>. This interface
    provides the connection to specific methods and contains some other
    descriptive data for controllers like menus and toolboxes, but also
    for the various APIs. The main part of the interface description is in
    the form of a <Type-Library>, which is generated from an IDL-file by
    the <SVIDL-Compiler>. For each SfxShell Subclass-File there is one
    such IDL-file to write.
