 Description: 
    this is an analyzer that reads pat::CompositeCandidate WenuCandidates
    and creates some plots
 Implementation:
    The code takes the output of the WenuCandidateFilter and
    * implements on them  a user defined selection 
    * implements the selection with one cut (configurable which cut) inverted
    * creates a set of basic plots with the Wenu Candidate distribution
      vs MET, MT etc. These plots are stored in a root file
    If you have several root files from different runs you have to run a macro
    to combine the output and have the final plots

    This analyser is PAT based in the sense that it reads CompositeCandidates,
    which are composed of a pat::MET plus a pat::Electron. You normally
    don't have to change this file when the CMSSW version changes because it
    contains only methods from the stable core of pat Objects. Most
    version dependent changes should be in WenuCandidateFilter.cc
 TO DO LIST:
    * more plots to be added
    * there should be an base Plots class from which WenuPlots and ZeePlots
      inherit. this makes sense since they have so many common methods

  Changes Log:
  12Feb09  First Release of the code for CMSSW_2_2_X
  16Sep09  tested that it works with 3_1_2 as well 
  09Sep09  added one extra iso with the name userIso_XX_
  23Feb09  added option to include extra IDs that are in CMSSW, such as
           categorized, likehood etc
           added extra variables TIP and E/P  
  27May10  changes to apply the Spring10 selections, relative isolations
           the 3 default ones, pat user isolations added in the end
           change to framework independent variable definitions 
       double->Double_t etc and math.h functions from TMath
  01Jul10  second electron information added
