Personally, I find the bounding box somewhat redundant, but I guess
that's a matter of taste. The attached version extends the
documentation, and adds a demonstration, plus some minor code changes to
plot the ellipses if less than two outputs are requested (if one is
requested a handle is returned).

The attached version only plots the ellipse, and its major/minor axes,
because that's what I prefer. But as I said that's really a matter of
taste, so there should probably be some way of changing what
specifically is plotted. I'm just not sure what the best API for doing
this might be. Suggestions are more than welcome...
