/* 
 * class PFRecoTauDiscriminatioLogicalAndProducer
 *
 * Applies a boolean operator (AND or OR) to a set 
 * of PFTauDiscriminators.  Note that the set of PFTauDiscriminators
 * is accessed/combined in the base class (the Prediscriminants).
 *
 * This class merely exposes this behavior directly by 
 * returning true for all taus that pass the prediscriminants
