1.需求:使用suimove实现购买股票，根据股票分红sui支持把钱转给一个对象地址，提供一种机制，将对象地址拥有的钱，提取到这个对象的owner的钱包。如下图,12:用户A发布合约,拥有分红权限34:用户B花钱购买了股票,合约里面增加了钱5:将股票自由转移
1.需求: 使用sui move 实现购买股票，根据股票分红
sui 支持把钱转给一个对象地址， 提供一种机制，将对象地址拥有的钱，提取到这个对象的owner的钱包。
如下图,
1 2 : 用户A 发布合约,拥有分红权限
3 4 :用户B 花钱购买了股票 ,合约里面增加了钱
5 : 将股票自由转移给C,不需要通知用户A
6 :用户A 分红,将分红发给股票, 这个例子里面分红20%
----这里可能经过了很多运营,合约里面的钱增值了, 本文不涉及相关逻辑
7 :用户C 拿着股票,到合约来领取分红到钱包
2. 样例代码

//阶段性分红，percent： 百分比乘以10000， 根据份额，把一部分钱发给股票

//分红发到股票地址
transfer::public_transfer(coin, share.id);
};

}
}
// 将股票拥有的钱提取到股票拥有者的钱包.只有拥有股票的人才能使用这个stock参数
