Changed

* 41ed5720
* deepcopy of inputs: since the dictionaries/sets are modified, a "deepcopy" is the best option to ensure data
integrity.
* keep_all_activities parameter in paths filter: decides if all the activities (also the ones connected by the
low occurrences edges) should be kept, or only the ones appearing in the edges with more occurrences (default).
