9//======================================================================
10// AliGenPHOSlib class contains parameterizations of the
11// pion, kaon, eta, omega, etaprime, phi and baryon (proton,
12// antiproton, neutron and anti-neutron) particles for the
13// study of the neutral background in PHOS detector.
14// Additional particle species simulation options has been added:
15// Charged Pion, Charged Kaons, KLong Proton, Anti-Proton, Neutron,
16// Anti-Neutron --> Changes made by Gustavo Conesa in November 2004
