Does hierarchical decomposition of points. Works by first sorting the points in x direction into equal sized bins, then in y direction and finally in z direction.
Uses single array to hold decomposition which is indexed as if it is a 3 dimensional array:
finalDecomp[i,j,k] is indexed as
i*n[0]*n[1] + j*n[1] + k
E.g. if we're sorting 'xyz': the first sort (over the x-component) determines in which x-domain the point goes. Then for each of the x-domains the points are sorted in y direction and each individual x-domain gets split into three y-domains. And similar for the z-direction.
Since the domains are of equal size the maximum difference in size is n[0]*n[1] (or n[1]*n[2]?) (small anyway)
