/** 
   Compact-views can be created only after an appropriate geometrical hierarchy
   has been defined using DDpos(). 
      
   Further it is assumed that the DDLogicalPart defining the root of the
   geometrical hierarchy has been defined using DDRootDef - singleton.
   It will be extracted from this singleton using DDRootDef::instance().root()!
      
   The first time this constructor gets called, the internal graph representation
   is build up. Subsequent calls will return immidiately providing access to
   the already built up compact-view representation.
      
   Currently the only usefull methods are DDCompactView::graph(), DDCompactView::root() !
       
   \todo define a stable interface for navigation (don't expose the user to the graph!)
