polyMeshMap: New mesh to mesh map for the new mapping update function mapMesh(const polyMeshMap&)

This new mapping structure is designed to support run-time mesh-to-mesh mapping
to allow arbitrary changes to the mesh structure, for example during extreme
motion requiring significant topology change including region disconnection etc.
