 * Represents a class that loads UserInterface objects from Doctrine source for the authentication system.

 * This interface is meant to facilitate the loading of a User from Doctrine source using a custom method.
 * If you want to implement your own logic of retrieving the user from Doctrine your repository should implement this
 * interface.

 * @see UserInterface
 *
 * @method UserInterface|null loadUserByIdentifier(string $identifier) loads the user for the given user identifier (e.g. username or email).
