Simplification of Neo4j::Server::CypherResponse::HashEnumeration
Create Query#break method to allow for calling clauses multiple times, when desired.  Use break implementation to make WITH implementation simpler
A start on implementing params for Query objects
Implementing pluck and CypherResponse#to_node_enumeration to start being able to support ActiveNode
Merge branch 'master' into query
Fix pluck (should use the temporary built query rather than self
Shoring up CypherResponse#to_node_enumeration.  Takes HashEnumeration and turns hashes into CypherNode objects.  This should also support CypherRelationship objects
Support nil value as "IS NULL"
