/**
* Class used to interact with the Metal service, a managed retrieval &
* memory platform. It allows you to index your data into Metal and run
* semantic search and retrieval on it. It extends the `BaseRetriever`
* class and requires a `Metal` instance and a dictionary of parameters to
* pass to the Metal API during its initialization.
* @example
* ```typescript
* const retriever = new MetalRetriever({
*   client: new Metal(
*     process.env.METAL_API_KEY,
*     process.env.METAL_CLIENT_ID,
*     process.env.METAL_INDEX_ID,
*   ),
* });
* const docs = await retriever.getRelevantDocuments("hello");
* ```
