GraphDB configuration variables

[jvwong]

• Configurable variables for the graph database (Neo4j)
• Driver code initializes if doesn't exist
• tests.

Hi @jvwong, it looks good to me! Definitely an improvement over the connect-neo4j.js edits I made over at my pr.
Good call making the username and password "undefined" instead of just ignoring it like I did!

Is this ready to be merged?

Sure I'll merge it in. You'll have to update your unstable branch locally, then you might want to add these changes to your test PR/branch. I don't think there will be conflicts (these updates and your updates overlap). In either case I figured this was a good practice of collab coding.

One more thing @lindajiawenli - the docs say that Driver.verifyConnectivity is deprecated (but only for some return type). So anyways that's why I got rid of it.

Yeah I noticed that too! Thanks for working around it.
