Initial conversion to Neo4j

Only basic searches (no correlated searches, no synonyms) at the moment.
Added neo4j csv-parsing dir
Removed error_reporting()
Removed neo4j, added swap

- Vim swap files (.swp)
- neo4j/ dir (moved to remote)
New query construction method

Uses one query string for everything. Also uses query parameters --
not sure if you can injection-attack Neo4j but good to stay on the safe side.
