/**
 * Provides a mechanism for removing handlers such as a {@link MessageHandler} or
 * {@link nats.client.MessageHandler} or to cancel recurring publishes.
 *
 * For example, when using a {@link nats.client.Subscription}, you may add a {@link nats.client.MessageHandler}
 * using the {@link nats.client.Subscription#addMessageHandler(nats.client.MessageHandler)} method. This method returns
 * an instance of {@code Registration}. When the {@link #remove()} method is invoked, the {@code MessageHandler} is
 * removed from the {@code Subscription} and will no longer be called when new messages arrive on the
 * {@code Subscription}.
