    Added Reverse-Cuthill-McKee reordering into INNER_MPTILUC preconditioner
    as default reordering when Metis_NodeND is not provided. On the tests
    RCM shows 10% more fill-in in inverse factors then with Metis_NodeND,
    but the RCM reordering procedure is 4 times faster then Metis_NodeND and
    overall computational time decreases with RCM.
