This function modifies the given 'bcurve' by removing knots.


Specific Errors:
    PK_ERROR_is_attached        'bcurve' is attached to topology (MILD)
    PK_ERROR_illegal_owner      'bcurve' is owned by other geometry (MILD)
    PK_ERROR_bad_index          an entry in 'knot_indices' is out of range
                                (MILD)
    PK_ERROR_bad_value          an entry in 'remove_multiplicities' is too high
                                (MILD)
    PK_ERROR_bad_tolerance      'tolerance' is invalid (MILD)


This function modifies a b-curve by removing knots, if possible.

A b-curve cannot be modified if it is attached to topology or if it is owned
by other geometry.

The number of distinct knots removed, if any, is returned in
'n_knots_removed'.  The values of any knots that were removed will be returned
in 'knots_removed' and the number of times each of these knots was removed,
i.e. the decrease in its multiplicity, will be returned in 'multiplicities'.

See here for more information about modifying B-curves.
