Stix-2.x conversion tool

[ringo <ringowathelet@gmail.com>]

I don't know Neo4j at all, but it looks interesting. From my initial read, there is 

an "import" tool for bulk csv files. So I may start with generating the 

appropriate csv files to store all the Stix info into a Neo4j database.

Before I start hacking away, has anyone already done this?
