// cuts can be defined as C/C++ conditional expressions. To simplify  //
// these expressions, equivalences (alias expresions) can be created. //
//                                                                    //
// The output of this class is a set of TNamed objects located in     //
// subfolders "Cuts Expressions" or "Equivalences" in "Cuts"          //
// TDirectory. The cuts and equivalences names are contained in the   //
// Name of the object and their expression is located in the Title,   //
// such that these strings can be read using TNamed::GetName() and    //
// TNamed::GetTitle()                                                 //
