Attribute "FWHM"?

See original GitHub issue

I have realized that Fittable1DModel and Fittable2DModel (including Gaussian and Moffat) has no attribute of FWHM, while quite many of them actually need it for astronomical purposes.

A built-in function astropy.stats.gaussian_sigma_to_fwhm can be used only for Gaussian, while we need much more functions’ FWHM values in practice.

I guess it will be very useful if we have something like attribute to calculate FWHM.

I suggest we take a minimal approach because it can easily get complicated. For all models for which this makes sense, have a getter property fwhm which computes fwhm from stddev. fwhm is not going to be a settable property and not allowed in __init__.

@ysBach - We usually keep issues open until the fixes are merged. In most cases the merge will auto-close them.
