Ok, @mmartinoli87 I have written a draft in Python of the MCS code. It would be great if you could add a few more line of comments to the R code, and specifically where I ask questions in this commit 9244d57.

The code seem to work already, but we are still thinking about the best way to integrate it within the Black-it pipeline. It might be useful to discuss this together, considering that we also want to integrate your recent article (https://scholar.google.it/citations?view_op=view_citation&hl=it&user=bJcPI-4AAAAJ&sortby=pubdate&citation_for_view=bJcPI-4AAAAJ:YsMSGLbcyi4C) which makes use MCS as a sub-tool.
