//! Document processing chains
//!
//! Document processing chains that provide LLM processing capabilities for multiple documents:
//! - StuffDocumentsChain: Stuff all documents into a single prompt
//! - RefineDocumentsChain: Iteratively refine the answer document by document
//! - MapReduceDocumentsChain: Process documents in parallel then merge results
//! - MapRerankDocumentsChain: Process documents in parallel then rank by relevance
