Implement Graph Memory in AI Assistant

[Aftar-Ahmad-Sami]

Description

This pull request adds a new Jupyter notebook to the mem0 cookbook, demonstrating an AI companion application that utilizes mem0's graph memory capabilities. The notebook showcases how to create an interactive AI assistant that can remember and recall information from previous conversations using OpenAI's GPT-4 model and mem0's memory system.

Key features:

• Integration of OpenAI's GPT-4 with mem0's memory management
• Utilization of Qdrant for vector storage and Neo4j for graph storage
• Interactive conversation loop with memory retention and retrieval

This addition aims to provide mem0 users with a practical example of building an AI companion system, highlighting the power of graph-based memory in conversational AI applications.
