`Ellipse`/`Ellipsoid` classes

[CristianoPizzamiglio]

Hi!

This is not an issue, but just a discussion.

Have you ever thought about adding Ellipsoid and Ellipse classes? Similar to the Sphere/Circle classes, we could create a _BaseEllipsoid class which is inherited by both Ellipsoid and Ellipse classes. I am glad to help if you consider this valuable.

By the way, what about adding the Discussions tab for this library? Maybe it's too early?

Thanks!

Hi, I'm on vacation so I may not respond for the next two weeks.

This sounds like it could fit with the library so feel free to make a PR.
