  \brief Jet producer to produce compound jets (i.e. jets of jets)

  \author   Salvatore Rappoccio
  \version  

         Notes on implementation:

         Because the BaseJetProducer only allows the user to produce
         one jet collection at a time, this algorithm cannot
         fit into that paradigm. 

         All of the "hard" jets are of type BasicJet, since
         they are "jets of jets". The subjets will be either
         CaloJets, GenJets, etc.

         In order to avoid a templatization of the entire
         EDProducer itself, we only use a templated method
         to write out the subjets to the event record,
         and to use that information to write out the
         hard jets to the event record.

Modifications:
         25Feb09: Updated to use anomalous cells, also 
                  included corrected CaloTowers for the PV.
