bug#26807: [PATCH] graph: Add Cypher backend.

Description: Text Data

Dear Guix,

I would like to add another backend to the 'guix graph' command.  This
backend will return a bunch of queries that can be used to create a
graph database for any database engine that uses openCypher (although I
only know one engine and it's called neo4j, which should be GPLv3 code).

If there was a way to ensure node definitions are written to the output
before the edges, I could simplify the queries a bit.  But I believe it
is quite fast anyway.

Thanks!

Kind regards,
Roel Janssen
