//
// Classe to create the MUON coktail for physics in the Alice muon spectrometer
// The followoing muons sources are included in this cocktail: 
//     jpsi, upsilon, non-correlated open and beauty, and muons from pion and kaons.
// The free parameeters are :
//      pp reaction cross-section
//      production cross-sections in pp collisions and 
//      branching ratios in the muon channel
// Hard probes are supposed to scale with Ncoll and hadronic production with (0.8Ncoll+0.2*Npart)
// There is a primordial trigger wiche requires :
//      a minimum muon multiplicity above a pT cut in a theta acceptance cone
//
