Detailed Description

Remove duplicates from the list of electrons.

The DuplicatedElectronCleaner removes duplicates from the input collection. Two electrons are considered duplicate if they share the same gsfTrack or the same superCluster. Among the two, the one with |E/P| nearest to 1 is kept. This is performed by the DuplicatedElectronRemover in PhysicsTools/PatUtils

The output is an edm::RefVector<reco:::GsfElectron>, which can be read through edm::View<reco::GsfElectron>
