/**
* A {@link Repository} that can receive new data through {@link Receiver#accept(Object)}.
*
* <p>If the new data does not {@linkplain Object#equals equal} to the old data, the added

*
* 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>
