This function deletes interior loops from a sheet body.


Specific Errors:
    PK_ERROR_not_sheet             the body containing the given loops is not
                                   a sheet body
    PK_ERROR_missing_geom          sheet has no surface attached
    PK_ERROR_unsuitable_loop       loop is not an interior loop


All of the given loops must be interior loops and they must all
belong to the same sheet body.  That sheet body must have at least one face
to which a surface is attached.  Each loop may either consist of wire edges
or it may bound a hole.
