Expand RecHitPlotter: split endcap, add HF, etc.
Introducing CaloTowerPlotter.

Still very basic.  Only plots essential quantities, not split up by
subdetector yet.
Add more plots to TrackPlotter.

Not all quantities are understood currently, e.g. everything starting with
reco::Tracks::d does not seem to be comparable (yet).
Add folding for input files to create_plots.py.
Small fix to argument parsing.
Fix running over MC raw.
Print trigger summary independetly of data type.
Update for no PU stuff.
Shuffle some fragments around.
Create empty source by default.
Let p_T cut in TrackPlotter affect all quantities.
Mark some plots WIP in TrackPlotter.

Don't know if I'm going to fix these in the future.  There are
enough other quantities being plotted, as far as I'm concerned.
Crab configurations to run over 2012C stuff.
Better directory handling when saving plots.
Update RecHitPlotter to include sum(et) vs #vertices.
Plot with more cuts.
Plotting with raw & reco (and use_parent).
Reworking of plot saving code.
