    (List)     checking_criteria  - List of checking criteria.
    (Number)   tolerance          - Smooth tolerance
    (Integer)  u_sample_points    - Number of sample points in u direction
    (Integer)  v_sample_points    - Number of sample points in v direction
    (Name)     log_option         - LOG_ERROR, LOG_WARNING, LOG_INFO, LOG_NONE.
