Detailed Description

template<class ObjectType>
class pat::PATUserDataHelper< ObjectType >

Assists in assimilating all pat::UserData into pat objects.

      This will pull the following from the event stream (if they exist) and put them into the
  object in question, all indexed by the reco objects that make up the pat objects in question:

    ValueMap<double>
    ValueMap<int>
    ValueMap<Ptr<UserData> >
    ValueMap<CandidatePtr>

  This is accomplished by using PATUserDataMergers. 

  This also can add "in situ" string-parser-based methods directly.
