<B>Description:</B>
  Checks interior knots of B-spline surfaces and finds problems with bad
  multiple knots, decreasing knot sequence, bad end knots, and adjacent knots
  that violate the multiple knot tolerance.

<B>Input:</B>
  (List)      geometry_set      - List of {all_in_part:, {curve_set:},}
  (List)      topo_tolerances   - List of {distance:, tangent_angle:, curvature:}
  (List)      checking_criteria - List of checking criteria.
  (List)      selection_filters - List of selection filters.
  (Number)    tol               - Multiple knots contraint value.
  (Name)      log_option        - LOG_ERROR, LOG_WARNING, LOG_INFO, or LOG_NONE;
  (String)    error             - Error message

<B>Input Arguments:</B>
geometry_set
topo_tolerances
checking_criteria
selection_filters
tol
log_option
Error

<B>Returns:</B>
0      - Passed - No faces will be reported.
   non 0  - Error  - Faces with knot problems.
Note:
   Objects logged - B-spline faces.
