 - See example csv [here](/importer/csv/import/product.csv)
 - This creates a Group resource for each product imported, a Binary resource for any products with an image, and a List resource with references to all the Group and Binary resources created
 - The first two columns __name__ and __active__ is the minimum required
 - The last column __imageSourceUrl__ contains a url to the product image. If this source requires authentication, then you need to provide the `product_access_token` in the config file. The image is added as a binary resource and referenced in the product's Group resource
+- You can pass in a `list_resource_id` to be used as the identifier for the List resource, or you can leave it empty and a random uuid will be generated
