//
// In this class the models for ion-ion interactions at intermediate energies (0 - 1 GeV per nucleon)
// can be activate. This class can be used alternatively to the "binary_ion" physics list
//
// The usefullness of this class is that you can explicitally see the total inelastic sections
// activated and the models called. Moreover you can choose to activate for ions (from deuteron
// to heavier nucleus) three different and exclusive models: the Binary Light Ion cascade, the QMD
// and The Wilson.

// For hadrotherapy pouposes, where distributions of produced fragments is importante we strongly
// suggest to use Binary or QMD. The Binary model is the default and at moment, you can swith beetween models decommenting
// the line of code and recompiling
