Class
    Foam::faMesh

Description
    Finite area mesh (used for 2-D non-Euclidian finite area method)
    defined using a \em patch of faces on a polyMesh
    (ie, uindirectPrimitivePatch).

    The ordering of faces and points on the faMesh corresponds to
    the localFaces and localPoints as per Foam::PrimitivePatch but
    the edge addressing is handled slightly differently.
    The internal edges of the faMesh will generally correspond identically
    to the internalEdges of the PrimitivePatch (may change in the future)
    but the boundaryEdges will be reordered compared to the PrimitivePatch
    to allow edge boundary slices to be obtained.
