Edge Classes: create a property and a unique index on Neo4jRelID

[santo-it]

This will improve how migrated relationships can be queried by original Neo4j relationship ID

Possible Workaround:

• using Studio or the Console, on the E (edge) class, create a property named Neo4jRelID and then a unique index on this property. This will allow you to query relationship by neo4j id using a query like:

select * from E where Neo4jRelID = your_id_here

The fix adds a command line option -i, default to false. When -i is true the Importer will create a unique index on the property Neo4jRelID, for all migrated edge classes. This will allow users to query relationships by original neo4j relationship ids
