          The number of sampling points to use.  Think of this as
          a sampling of the unit hypercube.  So to compare it to
          N, the number of points, you need to take its M-th root.
          In 2D, if you're using 10 generators, and 100 sample points,
          to get area and sampling computations twice as good requires
          4 times the sampling.  I
