Detailed Description

Generic analyzer for Di-Leptons.
See ZMuMuAnalyzer for a concrete case.

Example configuration, and list of parameters:
#O means optional

ana = cfg.Analyzer(
  'DiLeptonAnalyzer',
  scaleShift1 = eScaleShift,  #O shift factor for leg 1 energy scale
  scaleShift2 = tauScaleShift,#O same for leg 2
  pt1 = 20,   # pt, eta, iso cuts for leg 1
  eta1 = 2.3,
  iso1 = None,
  pt2 = 20,   # same for leg 2
  eta2 = 2.1,
  iso2 = 0.1,
  m_min = 10,    # mass range
  m_max = 99999,
  dR_min = 0.5,  #O min delta R between the two legs
  triggerMap = pathsAndFilters, #O, necessary for trigger matching
  verbose = False               #from base Analyzer class
  )

COLIN: need to specify what is needed in the event.
COLIN: need to make delta R non optional.
COLIN: make the dR_min parameter non optional
