Neo4J TraversalDescription Definition
===

I am trying to create a **TraversalDescription** that will perform the following search;

 - Return only nodes that have a certain property ("type" == "PERSON")
 - Return a certain fixed number of results (the entire graph is huge, we are only interested in the local graph)
 - Any relationship types can be used

I haven't managed to get very far, I can't seem to figure out how to create an Evaluator for node properties;

    TraversalDescription td = Traversal.description().bredthFirst().evaluator(?...);
