// 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 ("//!")                                           //
//                                                                          //
