<B>Description:</B>
Check that the surface geometry is valid geometry and is not
self-intersecting with an option to check spike and cut.

<B>Input:</B>
    (List)    geometry_set      - List of geometry set
                                  {all in part option, {geometry entities}}
    (List)    topo_tolerances   - List of topological tolerances
                                  {distance topological tolerance,
                                   tangent angle topological tolerance,
                                   curvature topological tolerance}
    (List)    checking_criteria - List of checking criteria
    (Number)  tolerance         - Distance tolerance
    (Boolean) spike_cut         - Check spike and cut
    (Name)    log_option        - LOG_ERROR, LOG_WARNING, LOG_INFO, LOG_NONE.
    (String)  message           - Character string of error, warning, or info.
    (Number)  angle_tol         - Angular tolerance for spike and cut
