Hi,

The current sigma clipping function has no iters keyword.

I feel it would be useful to include it in the function, with a default like `iters=None` so that if people do want to use the keyword they will be able to do so.

With the defaults of `iters = None` it shouldn't break anyone's workflow and will correspond to the current default behaviour.

If there is any interest in this, I can file a pull request soon.

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.
