The LundFragmentation class handles the default Pythia fragmentation, using both the StringFragmentation and MiniStringFragmentation classes.

overridevirtual |
Do the fragmentation: driver routine.
String fragmentation of each colour singlet (sub)system. If fails optionally try ministring fragmentation.
Low-mass string treated separately.
Return successful.
Implements FragmentationModel.

overridevirtual |
Initialize and save pointers.
Register the string and ministring fragmentation models.
Set the pointers.
Boundary mass between string and ministring handling.
Try ministring fragmentation also if normal fails.
Return successful.
Implements FragmentationModel.
