RecoTauTag/RecoTau: clean -Wunused-function warnings

Signed-off-by: David Abdurachmanov <David.Abdurachmanov@cern.ch>
Added module for centralized jet source selection
added jet filtering
reduce inefficiency of anti-muon discriminator in high pile-up events:
	- do not veto track segments in innermost CSC chamber
	- count number of muon stations containing matched segments
	  rather than summing matched segments of different muons in the same muon station
	 (in the old implementation a tau was failing the anti-muon Loose discriminator in case there are 2 reco::Muons
	  each having 1 matched segment in the innermost CSC chamber. The new implementation requires that the matched segments are in at least 2 different chambers
	  before the tau fails the anti-muon discriminator)
removing the filter for the time being
Adding hooks for jet filtering
modified default filtering parameters
- fixed inefficiency of anti-muon 2 discriminator at high eta in events with high pile-up
- improved decayModeFinding efficiency in events with high PU
fixed syntax error
