Describe the process of handling requests and responses in Slim Framework.

Answer: In Slim Framework, handling requests and responses involves the following steps:

1. Routing: When a request is received, Slim matches the request URL and HTTP method to predefined routes defined in the application.

2. Middleware: Before reaching the route handler, middleware can be executed to perform tasks such as authentication or logging.

3. Request Object: The matched route invokes a callback (controller) function, passing a `Request` object that contains request data (like query parameters, post data, etc.).

4. Response Object: Inside the route handler, you create or modify a `Response` object to construct what will be sent back to the client.

5. Return Response: Finally, the response object is returned from the route handler, and Slim sends it back to the client, completing the request-response cycle.

This process allows for clear separation of concerns and a flexible way to handle web requests.
