   DESCRIPTION
    Test equality helper using bidirectional properties

   NOTES

      SDO59-DeepCopy.doc

    mfobrien    09/14/06 - Creation
    mfobrien    09/18/06 - Add bidirectional testcases for the following cases

                                   - verify all properties that are bi-directional are type.dataType=false - spec 8.4
                                   - test bi-directional with one end at containment=true - spec 8.4
                                   - test bi-directional where both ends have the same value for readOnly = true - spec 8.4
                                   - test bi-directional where both ends have the same value for readOnly = false - spec 8.4
                                   - test bi-directional with containment where the non-containment Property has many=false. - spec 8.4
    mfobrien    09/18/06 - add unidirectional tests (inside/outside) copy tree
