The new method TopExp::MapShapesAndUniqueAncestors has been implemented, which excludes duplication of ancestors in the list items. The optional Boolean argument 'useOrientation' of this method points whether two same shapes with different orientation will be considered equal. OCCT code has been inspected and MapShapesAndAncestors has been replaced with MapShapesAndUniqueAncestors where it is necessary.
