Typo for ionization energy loss of tau lepton #6

Hi, I found a typo in Simu_elost.cxx: line: 847. It is "f=Cbb1/(b2)(log(Cbb2b2gammagamma/I2)-2b2+EEEE/(4x[0]x[0])-delta(X));" I think there should be a lost "EE": "f=Cbb1/(b2)(log(Cbb2b2gammagammaEE/I2)-2b2+EEEE/(4x[0]*x[0])-delta(X));" , according to Equation A.2 in hep-ph/0012350. For ~EeV level, alpha ~ 4MeV/(g/cm2).
