Code files for Synthesize answers over multiple individual Vector Indices with Llama index composable graph video (Patreon)

This is for video: https://youtu.be/GOIhpF38-GY

In this video we will explain how to use the LAMA Index for building composable graphs. These graphs allow you to build indexes on top of other indexes, which is beneficial when you want to query multiple indexes at the same time, something that would be difficult with traditional single index similarity searches due to the limit of chunks that can be fed into the large language model. We will also learn how we can use chat models such as gpt 3.5 turbo and gpt-4 with llama index
