Version 4.0.6

This is the last version that uses C++ objects in n3fit or validphys. It is also anticipated to be the last release that utilizes apfel for PDF evolution.

At the same time, it is the first version that includes a pineappl parser. pineappl is expected to become the main provider of theory predictions.
