  \class    pat::TrackerIsolationPt TrackerIsolationPt.h "PhysicsTools/PatUtils/interface/TrackerIsolationPt.h"
  \brief    Calculates a lepton's tracker isolation pt

   TrackerIsolationPt calculates a tracker isolation pt in a cone
   around the lepton's direction, without doing track extrapolation
