/* [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>.
