R script that sources individual_docs with different studyname

[sofiasiamp]

Should we have another R Script that just sources the individual_docs R file with different studyname? Not sure if the special spaces are the problem for that. In any case, such a very small script (similar to mock_data_initiation) should have a safe fail of asking if the user really wishes to proceed. That is because accidentally overwriting those files could be a bit nasty - we would have to revert a lot of files.
