    Added multilevel version of crout-ilu solver with maximum product
    transversal preordering on each level. The multilevel version is based
    on condition number estimation, factorization of rows with large
    condition number or small diagonal is postponed for the next level.
    Fixes for near-zero values in maximum product transversal algorithm and
    negative path-length.
    Fixes for output in DrawMatrix, option for text-based output for small
