 * Agera 中抽象出来的 可变仓库 接口
 * 继承了 数据接受者（ Receiver ）和 仓库（ Repository ）
 * 然而，仓库（ Repository ）接口 又继承了 被观察者（ Observable ）和 数据供应者（ Supplier ）接口
 * 就同时具备了它们（ Receiver, Observable, Supplier  ）的基本功能：
 * 1.作为被观察者，去通知观察者（ Updatable ）去更新数据
 * 2.作为数据供应者，去提供数据
 * 3.作为数据接受者，去接受外部数据
 *
 * 与 Reservoir 几乎一模一样。但是，Reservoir 中的 Repository 指定了 类型 Result<T>
