2// //
3// AliFemtoModelWeightGeneratorLednicky : the most advanced weight //
4// generator available. Supports a large number of different pair types //
5// and interaction types. Can calculate pair weights coming from //
6// quantum statistics, coulomb interation and strong interaction ot any //
7// combination of the three, as applicable. //
8// This class is a wrapper for the fortran code provided by Richard //
9// Lednicky. //
