TO DISCUSS: Improved naming
In this current state it is relatively easy to improve the wording of some classed & functions. Some of the naming is inconsistent or could be improved:
- Align: Some nodes contain "Node" in the name, others not: "ParallelNode" vs "Wait" decorator
- The blackboard access in nodes is an overly long name and not always consistent: "lookUpSymbolsInBlackBoard" in nodes and "lookUpSharedSymbols" in conditions. Maybe find a shorter name (& use it at all places)
