Description changed by strk:

Old description:

>
> This is similar to the existing toTopoGeom(Geometry, TopoGeometry) but
> works on TopoGeometries directly.
>
> The function as I see it should ONLY work at the topological level, so no
> conversion of any kind. The two argument TopoGeometries MUST belong to
> the SAME topology and need be of the same kind (simple or, hierarchically
> defined by the SAME lower layer)

New description:

 A function adding components of the second TopoGeometry to the definition
 of the first TopoGeometry.

 This is similar to the existing TopoGeom_addElement but adds all elements
 of the source TopoGeometry.

 The two argument TopoGeometries MUST belong to the SAME topology and need
 be of the same kind (simple or, hierarchically defined by the SAME lower
 layer)
