/*  [Description]
 
    In each SFx application one instance of the SfxBindings-Class will
    exists from <SfxApplication::Init()> until <SfxApplication::Exit()>.
    This instance is automatically created and destroyed by SfxApplication.
    However these instances will be handled by the Macro <SFX_BINDINGS>
    or the associated <SfxViewFrame>.
 
    The SfxBindings manages all of its Slot-Ids bound by the registered
    controllers and keeps a cache of the <Slot-Server> respectively.
    (it is what we call the combination of SfxShell instance and SfxSlot).
    In the SfxBindings it is stored, if and in this case which controllers
    that are dirty and which Slot-Server-Caches are dirty respectively.
    It summarizes status queries (calls to the status methods specified
    in the IDL) that are served by the same state methods, and handles
    the simulation of <Pseudo-Slots>.
