class Neo4jBulkCSVDataSink extends CsvGraphSource

This data sink writes a PropertyGraph into the Neo4j Bulk Import Format (see https://neo4j.com/docs/operations-manual/current/tools/import/).

In addition, it generates an import shell script that is parameterized with the path to the Neo4j installation and runs the import.
