Finds the hypervolume contribution for points in MD.
This implementation is slightly less naive. Instead of calculating Con{x S}=Hyp{S}-Hyp{S/x} directly, we restrict the volume dominated by points in S to be inside the box [x,ref]. This leads to points in S not being relevant for the computation and thus can be discarded using a simple dominance test.
