◆ adaptTauDiscriminator()

def TauDiscriminatorTools.adaptTauDiscriminator	(	discriminator,
		newTauProducer = `'shrinkingConePFTauProducer'`,
		oldTauTypeMapper = `recoTauTypeMapper`,
		newTauTypeMapper = `recoTauTypeMapper`,
		preservePFTauProducer = `False`
	)

Change a TauDiscriminator to use a different tau/prediscriminant sources

Tau discriminators use the following convention: 
     [tauType]DiscriminationByXXX

i.e. fixedConePFTauDiscriminationByIsolation,
allLayer1TausDiscriminationByIsolation, etc

However, the mapping of tauType to tau producer name is not constant.  In
RECO, the form is [tauType]Producer.  In PAT, the producer is just named
[tauType].  To manage this oldTauTypeMapper and newTauTypeMapper are
functions with signature f(str) that translate a TauProducer name (like
shrinkingConePFTauProducer) to its type (shrinkingConePFTau).  Two types of
mapping are provided, 
     * recoTauTypeMapper
           shrinkingConePFTauProducer->shrinkingConePFTau
     * producerIsTauTypeMapper
           allLayer1Taus->allLayer1Taus
