Data tests

One perfectly viable question one might have would be "why is the width ## instead of ##?" and that is a very good question. To help answer this question, I made the r command. This is to be run on an object with some continuum and in a wavelength range that is relatively flat. This then extracts the spectra using different widths, from 1 to 12. It outputs the flux and SNR inbetween where you selected with r.

use "v" to see error bars when you extract.
