Class
    Foam::polyDistributionMap
 
Description
    Class containing mesh-to-mesh mapping information after a mesh distribution
    where we send parts of meshes (using subsetting) to other processors
    and receive and reconstruct mesh.
 
    We store mapping from the bits-to-send to the complete starting mesh
    (subXXXMap) and from the received bits to their location in the new
    mesh (constructXXXMap).
