使用函数自动生成n层目录

先检查是否已经存在该目录了，如果存在，则不做任何处理，如果不存在则创建。
希望对各位快速开发有用。
CheckFolder.asp

\'***********************************************************************************************************
\'作 者: 赵敏 flash90@sohu.com
\'页面名称: CreateFolder.asp
\'页面功能: 生成n层目录的文件夹
\'使用方法: 调用CheckFolder()函数,例如: CheckFolder(path)
\'传入参数: 即将上传的文件的相对路径,例如: path = \"./upload/bbb/ccc/ddd\"
\'缺 点： 必须在参数path里面带上upload文件夹
