经理管理一个餐厅，推出每天都有特色菜的营销模式。他想根据一周中的每一天有一种特色菜。
客人想知道当天的特色菜是什么。另外再添加一个介绍页面。bios路径下，显示餐厅主人，厨师，服务生的简介。
python文件同级目录下创建templates，把所有模板都保存在这里。
厨师将当前特色菜品存储在一个json文件中。
{"monday":"烘肉卷配辣椒酱","tuesday":"Hamburger","wednesday":"扣肉饭","thursday":"泡菜锅","friday":"汉堡","saturday":"Pizza","sunday":"肥牛烧"} 把餐厅主任，厨师，服务生的介绍也保存在一个json文件中。
{"owner":"餐厅的主人","cooker":"帅帅的厨师","server":"美丽可爱漂亮大方的服务生"} python代码：datetime对象带有weekday函数，返回数字（0,1,2……）代表星期几
