​Hi Doug,

I'm happy to hear of the improvements to Sherpa, though I'm disappointed
that it's not compatible with matplotlib 1.5 and Numpy 1.10.  Do you expect
to overcome those incompatibilities soon?  I use anaconda, so to use Sherpa
at this point, I suppose I'd need to create an environment for it with
those different versions of matplotlib and numpy.
