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.
