At first I was really excited by this, but then I started looking it up, 
and there appears to be a lot of repetition in Halton point sets... I'll 
have to try the code you provided to see how well it distributes the points.

I usually just test new elements against all other elements and place a 
point where there is enough space by evaluating the radii. It's a slow 
method, but must only be performed once per-application if the points 
are saved to an .inc file.
