-- Creates a collection in an AWS Region. You can add faces to the collection using the operation.
--
--
-- For example, you might create collections, one for each of your application users. A user can then index faces using the @IndexFaces@ operation and persist results in a specific collection. Then, a user can search the collection for faces in the user-specific container.
--
-- This operation requires permissions to perform the @rekognition:CreateCollection@ action.
