added example for an event loop + histogram
Make plots of pull sigma vs k value.
Fit with exponential plus linear to check if k value choice is different.
updated rootpy
Changes to configs for k Value systematic.
Changes to scripts to include k +/- 1 systematic.
Add wait's at end of scripts.
Changes to config to include kValue systematic.
Changes to scripts to include k Value systematic.  Also fix bug in top mass systematic, where systematic was not being scaled for use in tables.
Remove extra space...
Remove debug printouts.
Add wait statement in x_04
Choose bin that fit reaches flat line rather than rounding to nearest integer.  Also remove alternative fit from being drawn.

Fixing travis
Added MC, muon channel; Added B-W fits; Fixed the pt and eta cuts for probes; Take into account all tags, removed matching to trigger for id/isolation tags; Added convoluted BW/CB plus exponential fit to Z peak; Background subtracted from Z peak fit binned in lepton eta/pt; Added 8 TeV CoM and MC plots; Added pickle files production
