-- $use
--
-- With batch mode you can issue several commands to Neo4j at once.
-- In order to issue batches you must use the Batch monad, parameters in batch mode can be actual entities already
-- obtained by issuing regular commands or previous batch commands, or even batch futures, that is you can refer
-- to entities created in the same batch, for instance:
--
-- > withConnection "127.0.0.1" 7474 $ do
-- >    g <- B.runBatch $ do
-- >        neo <- B.createNode M.empty
-- >        cypher <- B.createNode M.empty
-- >        B.createRelationship "KNOWS" M.empty neo cypher
-- >    ...
--
-- Batch commands return a "Database.Neo4j.Graph" object that holds all the information about relationships,
-- nodes and their labels that can be inferred from running a batch command.
