     程序:Wind股票数据下载
     功能:从Wind终端或者Wind资讯量化接口个人免费版中下载股票相关数据,保存至本地MySQL数据库,以进一步加工处理和分析
     创建时间:2016/01/15  V1.01 创建版本,Python2.7
     更新历史:2017/01/06  V1.02 从本地文件读取股票代码列表;升级到Python3.5版本
               2017/01/07  V1.03 封装为函数,便于调试和代码管理
               2017/01/08  V1.04 封装为类,为后续完善功能准备。自动从Wind中获取股票列表,独立运行;增加日志和参数处理
    
     环境和类库:使用Python 3.5及第三方库pandas、WindPy、sqlalchemy
                 数据库:MySQL 5.7.16
                 Wind资讯量化接口 个人版(免费),可从Wind官网或大奖章网站下载安装,注册即可使用
