class AliDecayerExodus: public TVirtualMCDecayer


 Generate electron-pair mass distributions for Dalitz decays according
 to the Kroll-Wada parametrization: N. Kroll, W. Wada: Phys. Rev 98(1955)1355
 and generate electron-pair mass distributions for resonances according
 to the Gounaris-Sakurai parametrization: G.J. Gounaris, J.J. Sakurai: Phys.Rev.Lett. 21(1968)244

 For the electromagnetic form factor the parameterization from
 Lepton-G is used: L.G. Landsberg et al.: Phys. Rep. 128(1985)301

 Invariant mass distributions of electron pairs from resonance decays
 of rho, omega and phi
 using Gounaris-Sakurai function
Double_t Lorentz(Float_t mass, Double_t vmass, Double_t vwidth)
 Invariant mass distributions of electron pairs from resonance decay
 of jpsi (and it can also be used for other particles except rho, omega and phi)
 using Lorentz function
void Decay(Int_t idpart, TLorentzVector* pparent)
void Rot(Double_t* pin, Double_t* pout, Double_t costheta, Double_t sintheta, Double_t cosphi, Double_t sinphi) const
 Perform rotation
Int_t ImportParticles(TClonesArray* particles)
   Import particles for Dalitz and resonance decays
void Decay(TClonesArray* array)
 Replace all Dalitz(pi0,eta,omega,eta',phi) and resonance(rho,omega,phi,jpsi) decays with the correct matrix element decays
 for di-electron cocktail calculations
