Failings:
+ The distribution near the gamut surfaces has a characteristic
+ "buffer zone" layer that is not very nice. This is because
+ the surface concentrate the sufrace points forming a "force field".
+ It would be good to add a tweak factor to reduce this surface "gang effect".

+
The initial allocation of points to lower dimension surfaces
is a bit haphazard. It would be nice to have some mechanism
to add or subtract points to/from lower dimensional surfaces
if they were over or under sampled compared to everything else.

While the current algorithm meets many goals, such as minimizing the
maximum estimated error from any point in the space to the nearest
node, and placing nodes on sub dimensional surfaces with distributions
