+sparse_voxel_grid( p0, scalarFunc, eps, CV, CS, CI )
+Given a point, p0, on an isosurface, construct a shell of epsilon sized cubes surrounding the surface.
+These cubes can be used as the input to marching cubes.
+
+
+Parameters
+----------
+p0  A 3D point on the isosurface surface defined by scalarFunc(x) = 0
+scalarFunc  A scalar function from R^3 to R -- points which map to 0 lie
+            on the surface, points which are negative lie inside the surface,
+            and points which are positive lie outside the surface
+eps  The edge length of the cubes surrounding the surface
+expected_number_of_cubes  This pre-allocates internal data structures to speed things up
+
+Returns
+-------
+
+CS  #cube-vertices by 1 list of scalar values at the cube vertices
+CV  #cube-vertices by 3 list of cube vertex positions
+CI  #number of cubes by 8 list of indexes into CS and CV. Each row represents a cube
