An active model wrapper for the Neo4j Graph Database for Ruby.

Neo4j::ActiveRel::Persistence::QueryFactory#iterative_query

Each node must be either created or matched before the relationship can be created. This class does not know or care about
  how that happens, it just knows that it needs a usable Neo4j::Core::Query object to do that.
This method is "iterative" because it creates one factory for each node but the second builds upon the first.
