This function creates the topology of a wire body.


Specific Errors:
    PK_ERROR_bad_class             bad class in classes array
    PK_ERROR_bad_value             a value in parents or children array
                                   is not a valid index to classes array


Please refer to the documentation of PK_BODY_create_solid_topology.
This function is the same as PK_BODY_create_solid_topology with the exceptions
that the result is a wire body and the permitted classes and numbers of
children and parents are as follows:

--------------------------------------------------------------------
Entity    Children      No. of children   Parents     No. of parents
--------------------------------------------------------------------
Body      Shell               1             -             -
Shell     Face                1           Body            1
Face      Loops               1 or 2      Shell           1
Loop      Edges               >=1         Face            1
Edge      Vertices            <=2         Loops           2
Vertex    None                0           Edges           >=1
--------------------------------------------------------------------

Note that although a face and one or two loops must be present in the
input to this function, the created body has no faces or loops and the entries
in topols corresponding to these inputs are set to zero.
