class AliGenPHOSlib: public AliGenLib

  AliGenPHOSlib class contains parameterizations of the
  pion, kaon, eta, omega, etaprime, phi and baryon (proton,
  antiproton, neutron and anti-neutron) particles for the
  study of the neutral background in PHOS detector.
  These parameterizations are used by the
  AliGenParam  class:
  AliGenParam(npar, param,  AliGenPHOSlib::GetPt(param),
                            AliGenPHOSlib::GetY(param),
                            AliGenPHOSlib::GetIp(param) )
  param represents the particle to be simulated :
  Pion, Kaon, Eta, Omega, Etaprime, Phi or Baryon
  Pt distributions are calculated from the transverse mass scaling
  with Pions, using the PtScal function taken from AliGenMUONlib
  version aliroot 3.01

  Additional particle species simulation options has been added:
  Charged Pion, Charged Kaons, KLong Proton, Anti-Proton, Neutron,
  Anti-Neutron --> Changes made by Gustavo Conesa in November 2004
  Add flat Omega(782) distribution in Nov. 2010 by Renzhuo WAN
