/*
 * RecoTauBinnedIsolation plugin
 *
 * Abstract base RecoTauDiscriminantPlugin class that computes the bin content
 * of the isolation object p_T spectra.
 *
 * The binning is parameterized by the number of pileup vertices in the event.
 *
 * The extraction of the differnt objects to compute the spectra of is defined
 * in the derived classes by overriding the pure abstract extractIsoObjects
 * method.
