Just Running Pre-Release

This is the foundational release now that I've copied the code we are focusing on out of tomeichlersmith/ldmx-sim-technique.

I have been able to confirm that this compiles within that repository and runs DMG4 and G4DB simulations. I still need to validate that this technical changes do not lead to any physical changes and I need to update the notes and documentation.
