Add a new feature CausalRAG into GraphRAG

[Chuan Xu (OzzyXu)]

Recently, I have been working on the CausalRAG proposed by the paper "CausalRAG: Integrating Causal Graphs into Retrieval-Augmented Generation". In essence, CausalRAG extracts and summarizes causal relationships from knowledge graphs to enhance response generation. Building CausalRAG on top of GraphRAG is therefore a logical and efficient approach. Will the community be interested in adopting CausalRAG as a part of GraphRAG if I implement it? Or is it better to keep them as independent projects? I would like to hear some feedback from the community. Thank you.
