// The MParContainer class is the base class for all MARS parameter      //
// containers. At the moment it is almost the same than ROOT's TNamed.   //
// A TNamed contains the essential elements (name, title)                //
// to identify a derived object in lists like our MParList or MTaskList. //
// The main difference is that the name and title isn't stored and read  //
// to and from root files ("\\!")                                        //
//                                                                      //
