   @dwitry i merged this to `master` a while back, but now i'm seeing some problems. when
i run tests i get:
   
   ```
   java.lang.RuntimeException: GraphFactory could not instantiate this Graph implementation
[class org.apache.tinkerpop.gremlin.neo4j.structure.Neo4jGraph]
   Caused by: java.lang.reflect.InvocationTargetException
   Caused by: java.lang.NoClassDefFoundError: org/neo4j/graphdb/factory/GraphDatabaseFactory
   Caused by: java.lang.ClassNotFoundException: org.neo4j.graphdb.factory.GraphDatabaseFactory
   ```
   
   and it doesn't occur before this change.  Note that if you try to build this on `master`
I think there's some new dependency conflicts (which is what I was trying to fix when I uncovered
this) based on https://github.com/apache/tinkerpop/commit/607224a92e443f712ca86b4b38e2fe9f92e405dc
but I tried changes before that one (including the very commit i merged from this PR) and
I still get the problem. If this issue doesn't get resolved I will need to revert the change.
   
   Any idea what might be wrong there?
