// This class analyzes the "Lep Tree" created by HBHEMuonOfflineAnalyzer
// It has two constructors using either a pointer to the tree chain or
// the file name where the tree resides
// There are 2 additional arguments:
//      mode (a packed integer) with bits specifying some action
//           Bit 0 : 0 will produce set of histograms of energy deposit,
//                     active length, active length corrected energy;
//                   1 will produce plots of p, nvx and scatter plots for
//                     each ieta
//               1 : 0 ignores the information on number of vertex
//                   1 groups ranges of # of vertex 0:15:20:25:30:100
//               2 : 0 ignores the information on track momentum
//                   1 separate plots for certain momentum range
//                     (the range depends on ieta)
//              3-4: 0 separate plot for each depth

//              5-6: 0 no check on iphi
//                   1 separate plot for each iphi
//                   2 separate plot for each RBX
//                   3 exclude the RBX specified by bits 6-10
//             7-11:   RBX # to be excluded (maximum 5 bits needed for RBX)
//               12: 0 varying ranges of p depending on |ieta|
//                   1 constant p ranges
//            13-15: 0 no cut on ediff; 1-4 cuts at 5, 10, 15, 20 GeV
//      modeLHC (integer) specifies the detector condition
