Finds the hypervolume contribution for points in 3DD.
The algorithm sweeps ascending through the z-direction and keeps track of of the current cut through the volume at a given z-value. the cut is partitioned in boxes representing parts of the hypervolume that is not hared with any other point. thus the sum of the volume of all boxes belonging to a point is making up its hypervolume.
The algorithm runs in O(n log(n)) time.
