Using the settings.cfg file inside the exported wilhelm

Playlist sub class for each experiment listed therein as well as the
file path names and checksums of the included files.
This information is useful only to check if the relevant source and stimuli
files for a given experiment change from one repository version to another.
If they have changed, we know the experiment has changed.
Return as dictionary of lists of tuples.
