<B>Description:</B>
Checks face self-intersecting.
It also checks that the edges of the face intersect only at vertices.

<B>Input:</B>
    (List) selected_faces - A list of UG faces tags
                            If the list is empty, then it checks all the
                            bodies in the part file.

<B>Input Arguments:</B>
selected_faces

<B>Returns:</B>
A list of two sub-lists:
    { face_list, msg_list }
    face_list contains faces which are self-intersecting.
    msg_list contains error message with each face.
    Format:
    { (list) {(integer)face_tag1,(integer)face_tag2,...,(integer)face_tagn}
      (list) {(string)message1,(string)message2,...,(string)messagen}
    }
Note:
    The function is replaced by mqc_askFaceSelfIntersection.
