Detailed Description

Description: <one line="" class="" summary>="">

Implementation: <Notes on="" implementation>="">

EDProducer of the tagged TauJet with the ConeIsolationAlgorithm. It returns two collections: base collection is the JetTag, and extended Collection which is the IsolatedTauTagInfo. The method implemented in the IsolatedTauTagInfo class are used to compute the discriminator variable. A trick is used to link the IsolatedTauTagInfo to a smart reference to the JetTag.
