This milestone is to track the work and the timeline for the refactoring LArG4 work required to define the final data products for the simulation.

At the moment LArG4 is limited to single phase chambers where the read out wires and field planes are immersed in the liquid.
To incorporate a Dual phase liquid argon TPC one needs to transport the electrons to the surface and then needs to deal with the extraction of electrons on the boundary between liquid and gaseous Ar into the gaseous medium and then the propagation and amplification of these electrons.

There are a number of tasks to accomplish this work.

Note, as indicated in the subtask, the original plan was to incrementally replace parts of the LArG4 code with the updated Geant 4 functionality and interfaces. But it looks like it is easier to do a full replacement.
