Remarks

The data provider key used to look up the core nodes of the bfs layering. The BFSLayerer will try to retrieve a data provider from the graph to be layered with this key. The looked up data provider should provide boolean values for the nodes of that graph. The boolean value signals whether a node is to be placed in the first layer or not.

If the are no nodes marked as core nodes then nodes with indegree 0 are considered to be core nodes.
