Overview

A shallow interface object to collect multiple Cypher statements. We have an explicit different interface (#add instead ot #run) from a regular transaction to clarify that we just collect statements without running them directly. As a result no subsequent statement can access the results of a previous statement within this collection.

Effectively, we wrap just multiple statements for a single HTTP API/Cypher transaction API request.
