Initial Commit

The Electron Energy Deposition is intended to simulate the electron
energy deposition in various materials.
Removed unnecessary code
Updated the geometry
Modified the run files

Modified the run files to use differnet energy ranges.
Added histogram bin sizes

Added the histogram analysis to the output
Decreased default electorn cut

Decreased the default electron cut
Added /det/update

Added the updating of the detector geometry in order to run the code
that changes the detector construction.
Changed primary generator action to G4ParticleGun
Fixed the run action includes for the G4ParticleGun
Changed build instructions and removed extra macros

Changed the build instructions to hopefully include the macros in the
project for XCode, and removed the non-working vis.mac
Renamed logical world volume

Renamed the logical world volume so that it matched with the volume name
needed by the PrimaryGeneratorAction
Changed the energy deposition collection
Removed the Histograms
Removed references to the histo manager
Minor formatting changes
Increased number of thickness points

Increased the number of thickness points and the energies to run
Removed space in run action

Removed some of the formatted space in run action
Increased run length

Obseved a very high variance in the energy deposition, but I don't think
it has anything to do with the run length, i.e. not a property of the
Monte-Carlo convergence.
