HLTJetTagWithMatching

I'm proposing to add the HLTJetTagWithMatching module in CMSSW.
This module is very similar to HLTJetTag.

HLTJetTag is a filter that pass events matching some requirements on the jetTag (eg. CSV>0.7).
It uses a jet InputTag only to fill the TriggerFilterObjectWithRefs.

HLTJetTagWithMatching is a filter that loop on a jet collection, and each jet is matched with the jetTag.
In this way it use the jet information from the jet collection, and the b-tag information by the jetTag collection.

With the new module, it will be possible, for instance, to have filter like "at least one jet with pT>50 GeV and CSV>0.7". In fact, you can produces a subset of jets and give it as InputTag to this module.

Cheers,
Silvio.
