Description

The [project board](https://github.com/astropy/specutils/projects/1) suggests that a continuum fitting routine is desired. This issue is intended to start a discussion about what functionality and interface would make sense, and I'm happy to implement what we decide on.

@andycasey and I have routine [at this link](https://github.com/andycasey/smhr/blob/master/smh/specutils/spectrum.py) that finds a continuum with iterative sigma clipping. It's meant to be used interactively, but could be ported over.

Research direction

Start by reading the issue discussion and the linked routine in smh/specutils/spectrum.py, which uses iterative sigma clipping to find a continuum. Clarify the desired functionality and interface before implementation; done requires agreement on that design and a corresponding continuum-fitting routine.
