复利计算再升级-----------------------------------------------------------

客户在大家的引导下，有了更多的想法：

1. 这个数据我经常会填.....帮我预先填上呗？......
2. 把界面做得简单漂亮好操作一点呗？
3. 能不能帮我转成个APP，我装到手机上就更方便了？
4. 我觉得这个很有用，很多人可能都需要这些功能，做到我的微信公众号上吧？
5. 能不能不要让我填表单，让我发条消息，或者对着手机说句话就可以了？

每组选一两个方向加以改进，让我们的投资计算与记录工具，达到可以发布给用户使用的版本，并发布博客对此次更新进行说明与总结。

任务分配

陈楷淇：1、完成主要代码
