0007  * Author: Christian Veelken, LLR
0008  *
0009  * Base classes for plugins that construct and rank PFRecoTauChargedHadron
0010  * objects from a jet.  The builder plugin has an abstract function
0011  * that takes a Jet and returns a list of reconstructed photons in
0012  * the jet.
0013  *
0014  * The quality plugin has an abstract function that takes a reference
0015  * to a PFRecoTauChargedHadron and returns a double indicating the quality of
0016  * the candidate.  Lower numbers are better.
