For clarity: this is stats.sigmaclip

Makes sense to me to add this.

I just saw that AstroPy has a much more extensive sigma clipping function.
Replacing stats.sigmaclip with
http://docs.astropy.org/en/latest/api/astropy.stats.sigma_clip.html would
be the way to go I think. In a backwards-compatible fashion of course, so
the `sigma` keyword from that function should be left out.
