Class
    Foam::mappedPolyPatch

Description
    Determines a mapping between patch face centres and mesh cell or face
    centres and processors they're on.

    Note:
        Storage is not optimal. It stores all face centres and cells on all
        processors to keep the addressing calculation simple.
