| Handle leftover nodes. Try to avoid singleton nodesIdea
In phase 3 we try to stick unaggregated nodes into a neighboring aggregate. We try to avoid singletons: we first try to build a new aggregate containing all neighboring non-aggregated nodes. If we cannot build a new aggregate, we add the non-aggregated node to the first adjacent aggregate. Only if there is no adjacent aggregate, we create a singleton node aggregate. More...
