Yes and no. The full Relate() method is still under construction (but
quite quite close).
You can test overlaps/touchs indirectly though, using the Distance()
function, which is good enough for the purpose. A Distance() = 0 implies
that the objects either touch, overlap, or contain; ie, they share some
part of their area.
