Remove functionality from imageutils that is in astropy

[astrofrog]

If we are going to keep this repository open for experimentation, we should nevertheless remove any functionality and close issues relating to things that are now in astropy master

[pllim]

:+1: Remove them but keep a warning statement that they now can be found in astropy.

[larrybradley]

:+1: I think that everything in imageutils got moved to astropy except for lacosmic, which is now in astro_scrappy. So this repo will effectively be empty.

[pllim]

So, is it time to "retire" this repo?

[astrofrog]

@pllim - yes, I think that would make sense, to avoid confusion on the part of users.

[pllim]

So maybe something like removing everything but __init__.py that now only prints a list of where all the functions have gone?

>>> import imageutils
WARNING: This package is retired. Here is a list of where its functions now reside:
blahblah() --> astropy.blahblah()
blahblahblah() --> astropy.blahblahblah()

If someone takes the time to go through what's here and the issues, and transfer this on Astropy issues or @larrybradley's https://github.com/spacetelescope/imutils, we should just delete this repo completely (along with it's issues).

It's a bit of work though to do that (not sure how much exactly), so that's why it hasn't happened. Any takers?

[pllim]

@embray , didn't you do a massive issues transfer once for ETC? Any advice?

[astrofrog]

There are only 16 issues open, so probably not too long to do by hand.

[larrybradley]

From a quick look, it appears most of the issues can be closed now. The rest should go to astropy.
