If i can do anything to simplify the review process, for me there is no
problem to split this PR into more activities; just one thing, for me the (c)
and (b) are one piece becouse the (c) expose the API used by (b) to visualize
the network.
I can make the (a) after we close (c)&(b) becouse it uses the new
[GraphResult
class](https://github.com/conker84/zeppelin/blob/master/neo4j/src/main/java/org/apache/zeppelin/graph/neo4j/Neo4jCypherInterpreter.java#L270).
Let me know how do you want proceed.
