working version; ids are still strange though;
indexing needs some love;
speed up of DB writing possible using batch imports etc
adding the jackson and jersey libs that the Neo4j REST binding depends on
partially tested version!
(tested on STRING action db)

This should serve as a discussion and concept release!

network-builder now supports:
writing to a Neo4j Database, either directly as an embedded DB or via REST

new cmdline parameters:
--neo4j: tells the system to write to a Neo4j Database

--out: location of the database; writes the DB to the specified location or if starting with http to the specified server

remark:
The Neo4jWriter uses AttributeName.Interaction as relationship type. all other properties are written to their nodes/edges as property. the node/edge ID is saved in the index "id":"id". Properties are indexed in "property":<name>

The Neo4jWriter is pretty slow when using the REST API for remote dbs. Optimized writing can be achieved via batch statements (planned after more testing).
