Using record data with the graph bundle

[Mike Thomsen]

I just approved and merged a PR from a colleague of mine to bring over
some code that we've been building for our client. It's a new
processor called ExecuteGraphQueryRecord. It allows users to build a
parameter map from dynamic properties that specify mappings between a
key and a record path.

Example usage:

Input:

{
  "name": "John"
}

Mapping:

name => /name

Cypher

MATCH (p:Person) WHERE p.name = $name RETURN p
