Possible two extra references

You most probably know the following two articles but if not please check if you think we should cite them in addition to the present references:

1. A manifesto for reproducible science:
   https://www.nature.com/articles/s41562-016-0021

2. 1,500 scientists lift the lid on reproducibility:
   http://www.nature.com/news/1-500-scientists-lift-the-lid-on-reproducibility-1.19970
