g0-merge: ASheathPotential relying on CUDA-aware MPI or broadcasting the wrong sheath potential #154

In the g0-merge branch, when running on GPUs, ASheathPotential is using Mpi.Bcast to broadcast the sheath potential. I think this either implicitly relies on CUDA-aware MPI or is just broadcasting the wrong potential. It should be revised.
