Yes, sure. I just said that there is an argument called
"extrema"
in aabb and that this argument can generally be avoided (which is what I was
doing it) if packing is generated first. To follow your suggestions,
"extrema" should always be specified, if one wants to append boxes first
than spheres. I think that a note on this would be nice.
