 Purpose : base class for all loggers. a logger can be 
           - stand-alone: it registers itself as oberver of all parts 
                    of the tasksystem, that it needs to fulfill
        his purpose
     - dependent: it does NOT register as observer and must be 
                  fed with events to do its work.
             This is used for loggers which are used by other loggers, 
       that must rely on a certain order in which update()-methods
       of dependent loggers are called.
