cosmic::BeamFlashTrackMatchTaggerAlg::BeamFlashTrackMatchTaggerAlg ( fhicl::ParameterSet const & p )

Title: Beam Flash<–>Track Match Algorithim Class Author: Wes Ketchum (wketc.nosp@m.hum@.nosp@m.lanl..nosp@m.gov), based on code from Ben Jones

Description: Algorithm that compares all tracks to the flash during the beam gate, and determines if that track is consistent with having produced that flash. Input: recob::OpFlash, recob::Track Output: anab::CosmicTag (and Assn<anab::CosmicTag,recob::Track>)
