创建Cookie：Micro.Cookie("名称", "值", { expires: 7 }, path: ‘/‘ );
expires：如果省略，将在用户退出浏览器时被删除。
path：的默认值为网页所拥有的域名
添加Cookie：Micro.Cookie("名称", "值");
设置有效时间（天）：Micro.Cookie("名称", "值", { expires: 7 });
设置有效路径（天）：Micro.Cookie("名称", "值", { expires: 7 }, path: ‘/‘ );
读取Cookie： Micro.Cookie("名称"});，如果cookie不存在则返回null
删除Cookie：Micro.Cookie("名称", null); ，删除用null作为cookie的值即可
