0013 
0014  GoodSeedProducer is the class
0015  for electron preidentification in PFLow FW.
0016  It reads refitted tracks and PFCluster collection, 
0017  and following some criteria divides electrons from hadrons.
0018  Then it saves the seed of the tracks preidentified as electrons.
0019  It also transform  all the tracks in the first PFRecTrack collection.
