0006  * class PFRecoTauDiscriminatioLogicalAndProducer
0007  *
0008  * Applies a boolean operator (AND or OR) to a set
0009  * of PFTauDiscriminators.  Note that the set of PFTauDiscriminators
0010  * is accessed/combined in the base class (the Prediscriminants).
0011  *
0012  * This class merely exposes this behavior directly by
0013  * returning true for all taus that pass the prediscriminants
0014  *
