Using specutils to fit for redshift with a template model

[eblur]

I started a tutorial for fitting an SDSS spectrum with a quasar template, and searching for the best fit redshift.

However, I'm running into technical problems. It's possible that this could be due to the nature of the InverseVariance uncertainty provided with the SDSS dataset. I am going to try translating the inverse variance into a StdDevUncertainty object and see if that works. If so, then we will need to submit an issue to the specutils repo.

It did not work. I opened two issues on the specutils repo, which refer back to this issue.
