Sounds great, Bill.
Some folks already did that, like 30 years ago...
Good job...

"Nevertheless, especially in higher dimensions, the bounding ellipsoid is
superior to the minimal cuboid in many ways. It is unique, whereas the minimal
cuboid is not. There is a reasonable algorithm to implement it. And it is a good
approximation of the object it contains, much better than the minimal cuboid."
