0009   \brief    Calculates a lepton's calorimetric isolation energy
0010
0011    CaloIsolationEnergy calculates a calorimetric isolation energy in
0012    a half-cone (dependent on the lepton's charge) around the lepton's impact
0013    position on the ECAL surface, as defined in CMS Note 2006/024
