   // will histogram the value of PARNAME for each event in which it is present.
   // (if the selection condition "PARNAME_M" is not used, the histogram will also be filled with a 0
   // for each event in which PARNAME does not appear).
   //          N.B. the PARNAME alias is in fact the sum of the values of PARNAME in each event.
   //          If PARNAME_M>1 in some events, it is not the individual values but their sum which will
   //          be histogrammed in this case.

   // If the option string contains both "arrays" and "leaves", then both structures will be used
   // (in this case there is a high redundancy, as each parameter is stored twice).

   // The full list of parameters is stored in a TObjArray in the list returned by TTree::GetUserInfo().
   // Each parameter is represented by a TNamed object.
   // In order to retrieve the name of the parameter with index 674 (e.g. taken from branch ParNum),
   // do:
   //     TObjArray* parlist = (TObjArray*) T->GetUserInfo()->FindObject("ParameterList");
