// Creates a collection in an AWS Region. You can add faces to the collection
// using the IndexFaces 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. When you
// create a collection, it is associated with the latest version of the face model
// version. Collection names are case-sensitive. This operation requires
// permissions to perform the rekognition:CreateCollection action. If you want to
// tag your collection, you also require permission to perform the
