Merge pull request #74 from kreczko/data_representation

Automatic binning
Redirecting outputs of measurement scripts to files.
Correcting typo.
Updating scripts for merging histograms files for both 7TeV and 8TeV.
Fixed so that maximum 8 jobs run simultaneously.
Updating config files for latest 7TeV measurement with v10 nTuples.
Adding Electron and Muon scale factor systematics.
Modifications to scripts to perform measurement on v10 7TeV 44X nTuples.
In all cases, added functionality to choose centre of mass energy. Commented out ptreweighting for 7TeV, will have to add back in at a later stage.
Fixing the pick binning procedure

Fixing the optimal binning procedure
Updating the unfolding pull checks for combination of channels
Merge pull request #77 from senkin/combined_pulls

Updating the unfolding pull checks
all variable binning information is now in one file
fixed latex definitions for geq
Formatting + added make_shape_comparison_plot function to tools/plotting.py
added bin/ to $PATH variable and made all scripts there executable
Updated file names and made writing the unfolding object optional
added convert_unfolding_histograms function to create a new set of unfolding files with appropriate binning. This speeds up the unfolding process by a factor of 200 compared to doing it every time (1 GeV bins!)
updated Timer to use time() instead of clock()
added "RAW" unfolding files which are used to create the ones we use for the measurement
added conditional_rebin function
