Combine publications for wiki

[alexfoias]

The problem is that we have to combine the publications for Julien & Nikola.

Nikola's independent publications (Julien not coauthor) are here.

We could add a Nikola sheet in this file. This will be used only when generating the references for our wiki. This solution will be simple because it doesn't require other credentials.

Another option would be to add the credentials for Nikola's independent publications in the script.

Great. I'll work on integrating the changes in the package.
