Detailed Description

Intermediate step in the L3 muons selection. This class takes the L3 muons (which are reco::Tracks) and creates the correspondent reco::RecoChargedCandidate.

Riccardo's comment: The separation between the L3MuonProducer and this class allows the interchangeability of the L3MuonProducer and the StandAloneMuonProducer This class is supposed to be removed once the L3/STA comparison will be done, then the RecoChargedCandidate production will be put into the L3MuonProducer class.
