Spack and CCfits

My Pull-Request for including the CCfits package in Spack has just been merged into the development version. Very nice!

I use spack extensively on our scientific clusters in order to provide environment modules with various software packages (and versions) to our users. And because we need the CCfits package, I've created this package for spack. Now it's upstream and I hope that it makes the work of many other system administrators easier.

Now back to work 🙂
