Robert probably has a better grasp of these issues than I, but it looks OK
to me. As to the documentation, I not quite sure if we have an Attributes
heading for classes, but I think so. I would just put it in svn because it's
easy for me to do, but I'm not up to speed on the documentation work flow
these days. Add a note as to the numpy version, i.e., .. versionadded::
2.0.0 .
