A `Into` clause contains the destination entity and destination persistent store for a `create(...)` method. A common usage is to just indicate the entity:

For cases where multiple `NSPersistentStore`'s contain the same entity, the destination configuration's name needs to be specified as well:
let person = transaction.create(Into<MyPersonEntity>("Configuration1"))
