Remove unused variable, complained during compiliation.
Histogram containing scale factors read in to muon.cpp
Scale factors read from histogram.
Fix bug in b jet weights.  Light jets with eta > 2.4 (but <2.5) giving zero weight.
Add option to read muon scale factors from file or not.
Added reading 7TeV muon trigger scale factors from histogram file.
Removing unnecessary cout statement.
abs/fabs bug fix; same as in NTupleProduction commit 3083f34e6c92b70bd43d321a3d414ba13be277c4.
Add electron id/iso scale factors and trigger efficiency histograms
