Removed orbital module

[dlakaplan]

#1974 : I don't know if this module is used. I suspect not. So delete to remove confusion.

[dlakaplan]

So the tests that fail are in tests/test_kepler.py. but again I don't see that used elsewhere, so not clear if those tests should also be removed.

@scottransom or @paulray : is this actually needed?

[scottransom]

I don't think it is needed. I just looked at the history and I think it was intended as being the core of a pure new orbit model that Anne Archibald was writing. But that obviously never happened. It is probably fine to get rid of it, although it seems like nice code!

I have no particular animus, but it can be a little confusing. Could just add some "DEPRECATED" notes to the files instead.

Yes, I think this is OK to remove. The code will be available in the git history if needed in the future.

[dlakaplan]

OK, in that case I think you can merge this.
