Initial Commit

Initial Commit.  This is based off of the GS20 light yield validation
study.
Added cmake
Added HistoManager

Added the histomanager.  I don't think that I will do the binning quite
like I did it for EnergyDepTracking as that didn't really work out.
Updated Materials

Updated the materials for the scintillator to be EJ-200 (based on
G4_Plastic_SC_VINYLTOLUENE)
Removed hadrons from physics list
Removed old macros
Added HistoManager

Added the histomananager.  I hope to use the same analysis structure,
working on rewriting all of it now
Added HistoManager
Removed AnalayisMessneger
Added SiO and others
Working analysis

Working Analysis, though the cleanup of geometry / runMnanager is
correct
Changed phyics list
Added macros and histograms
Added an electron run file

Added an electron run file
Runs, but not producing any secondary electorns :(

I want to simplify the geoemtry, and try again.
Reworked the geometry

Reworked the geometry, and a little bit of the materials
Reworked Primary Particle

Reworke the primary particle to use the simple particle gun
Fixed AbsorberSD references

Fixed the absorber SD references in the analysis.  I don't think that
this is quite want I want, but I want a bear bones implementation to
work off of.
Changed electron run
Switched to a simple geoemtry

Switched to a simple geometry.  Analysis is currently not working
