Fix change_node_name bug (!24) · Merge requests · Social Cognitive Systems / PRIMO

Jan Pöppel requested to merge jpoeppel:change_node_name_fix into master Oct 13, 2017

Created by: jpoeppel

Changing a node's name a second time resulted in a KeyError with the first new name due to an interesting property of allowing mutable objects as keys in dictionaries (didn't know that was possible before).

Kolja Berger also made the networks.py file more PEP8 compliant which I added to this PR.
