Generate analysis logfile
Summary
Aliby should produce a logfile with information on how the experiment ran and, more importantly, warnings.
Current behaviour/setbacks
Some components used to have logging, but it was deactivated when the structure was changed a year ago.
Desired behaviour/advantages
It would be easier to identify when and how things when wrong in the future, provided the logfile contains enough relevant information.
Implementation sketch
We can use decorators to log the steps (and even abstract them as an independent abstract base class). That would make this much more straightforward and simple.
