Great! I'll be working with this quite a bit so I do expect to contribute further. I've also subscribed to the StackOverflow tags in case there are others needing assistance with Isis + Neo4J.
Thank you Dan. Jeremy D.

Hi Jeremy, OK, I've merged in that pull request, thanks again for providing. I've also added a new page to the website, see [1] and [2] and updated the snapshot archetypes [3] (though probably still being built as I write this...) I've signposted all up as "experimental", so if you find any issues as you play with neo4j then do say.
