/**
* -------------------------------------------------------------------
* LtAutoloader要求：
* # 需要被自动加载的文件都以.php或者.inc结尾
* 如果既有php文件，又有html文件，html文件将被忽略，php文件正常加载
* 可配置，详情参见LtAutoloaderCofig
*
* -------------------------------------------------------------------
* LtAutoloader不在意：
* # 目录名有没有拖尾斜线
* # 目录下面有无子目录
* # 文件名和文件路径跟类名有无关联
* # 定义和使用类时，类名是大写还是小写
*
* -------------------------------------------------------------------
* LtAutoloader不支持（出错演示和不支持的原因参见WrongWayToUse.php）：
* # 传入的参数不是真实存在的目录（如http://some_dir这样的）
* # 目录名或者文件名带空格（如"Zend Framework"这样的目录名）
* # 类或接口重名，函数和函数重名
*
* -------------------------------------------------------------------
* LtAutoloader建议（不强求）：
* # 传入autoloadPath时使用绝对路径
* # 目录名和文件名只由字母、数字、下划线、中横线、小数点组成
* # 使用class而不是function来封装你的逻辑
* # 每个class都放在单独的一个文件中，且不要在已经定义了类的文件里再定义函数
* # class/function里不要使用__FILE__魔术变量
*
* -------------------------------------------------------------------
* 本测试用例期望效果：
* 在new CLASS_NAME, class_exists("CLASS_NAME"), extends CLASS_NAME的时候
* 自动把包含该类的文件加载进来
