This seems ok.
It is marked as draft, so I can check again when ready for review.

This PR adds distributed orthogonal mesh creation. This implementation differs from true distributed mesh creation in that rank 0 creates the entire global cell graph. This was intentional, as it allows the existing partitioning algorithms to work as is. After partitioning, rank 0 distributes partition and cell data to each rank, and the individual ranks build their own cells and populate the mesh.
Once this is tested at scale, I'll remove the "Draft" designation.
Closes #19
