/*
 * PFRecoTauChargedHadronPlugins
 *
 * Author: Christian Veelken, LLR
 *
 * Base classes for plugins that construct and rank PFRecoTauChargedHadron
 * objects from a jet.  The builder plugin has an abstract function
 * that takes a PFJet and returns a list of reconstructed photons in
 * the jet.
 *
 * The quality plugin has an abstract function that takes a reference
 * to a PFRecoTauChargedHadron and returns a double indicating the quality of
 * the candidate.  Lower numbers are better.
