Add data test to readme.
Add index of signal lepton to global event variables.
Add triggers for 2011 trigger efficiency studies.
Modify modules to record the index of the signal lepton in the selected lepton collection.  Also fix bug in loose muon selection.
Modify ntuple modules to store number of reconstructed primary vertices in an event, so can drop the full vertex collection.
Modify BLT configuration.  Remove default test files, add pdf weight producer, add global variables calcualted with two MET definitions, drop large uneeded collections.
Fix buggy input tags, add global event vars before both MET collections in muon channel, change prefix and suffix for global vars.
