AI powered expert system demo

This app shows how you can use LangChain4j to build an AI-powered system that:

Has access to terms and conditions (retrieval augmented generation, RAG)
Can access tools (Java methods) to perform actions
Uses an LLM to interact with the user

All credit for the example goes to LangChain4j, this demo simply expands on it by adding a React UI and a database.
