Merge remote-tracking branch 'origin/sibyl' into 'master'.

During the final days of the thesis, there were three branches.
“sibyl” for analyzing the data.
“report” fro writing the report.
“master” for some changes to the code base and other tasks.

This is the first commit to unify them.
It is important that the Sibyl work is now done.

This commit also introduces some parts of the report.
However this is an old version of it, that is present in the sibyl branch because I had to combine it with report at some point.
It should not be used.
