Make the graph database a configuration option

[dmccrearytg]

Our customers use TigerGraph, not Neo4j. This is because TigerGraph is a distributed graph, and can support queries over multiple servers. We want Med-Graph-RAG to work on existing healthcare graphs that already have billions of vertices and edges.

I want to work with this team to refactor the code so that the back-end database can be customized using some configuration file.

Please let me know your thoughts on this topic. I may not understand the code enough to understand the difficulty of this task.

@dmccrearytg I’m glad to see Med-Graph-RAG can interface with various graph servers. I believe it shouldn’t be too difficult to do. Feel free to submit a pull request, and I’ll review the code.
