Add rudimentary versions of path-specific efficiency plots
Add L2 and L3 tau efficiency plots

The efficiencies are now at least somewhat well-defined.
Calculate efficiency uncertainty with Clopper-Pearson via TEfficiency
Fix L1 tau and jet collection to one in AOD
Fix object type inferred from SingleMu and SingleEG
Clean up HLTTauDQMOfflineSource
Add high-pt efficiency plots
Take AND of PFTauDiscriminators instead of OR
Updated HLT_Tau_QualityTests.xml

Just to reflect the changes in histogram names
Update HLT tau validation configurations to updated HLT tau DQM code
Update HLT tau validation quality test xml
Fix high-pt L1 jet efficiency plot maximum pt
Fix deltaR matching in HLTTauDQMPath.cc

Permit trigger objects to be matched only one reference objects (mask
out already-matched reference objects). Allowing two trigger objects
to be matched to one reference objects can lead to incorrect numbers
in numerator or denominator (e.g. denominator being smaller than
numerator).
Add two LogErrors
Add missing places where axis labels should be copied
Update DQM and validation example job configuration files
Adjust binning, axis labels, and titles of plots
Improve printout
Include only L1 taus (no L1 jets) to L1Lead* and L1Second* histograms
