Features

• Sets up Swagger documentation for the API endpoints, using the swagger-jsdoc and swagger-ui-express packages.
• Initializes the SpotifyWebApi with the necessary client ID, client secret, and redirect URI.
• Calculates average values for certain audio features of the user's top tracks, and then uses those values to generate a set of recommended tracks.
