/*
 * RecoTauPiZeroPlugins
 *
 * Author: Evan K. Friis (UC Davis)
 *
 * Base classes for plugins that construct and rank RecoTauPiZero
 * 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 RecoTauPiZero and returns a double indicating the quality of
 * the candidate.  Lower numbers are better.
