00004  * class PFRecoTauDiscriminatioLogicalAndProducer
00005  *
00006  * Applies a boolean operator (AND or OR) to a set 
00007  * of PFTauDiscriminators.  Note that the set of PFTauDiscriminators
00008  * is accessed/combined in the base class (the Prediscriminants).
00009  *
00010  * This class merely exposes this behavior directly by 
00011  * returning true for all taus that pass the prediscriminants
00012  *
