//  扩展: 1, 项的后面,值的前面或后面可以有空格或TAB(2006_10_29)
//        2, 无法正常读取常用数据类型时有默认值返回.(2006_10_29)
//		  3, 读取字符串时提供一种不用释放的方式.(2006_10_29)
//		  4, 获取索引的连续项.(2006_11_08)
//		  5, 读取连续项数据(INT & STRING).(2006_11_08)
//		  6, 读写unsigned int(DWORD)类型(2006_11_08)
//		  7, 获取索引数量(2006_11_20)
//		  8, 根据索引号获取索引(2006_11_20)
//		  9, 条件编译可以不带LOG.h(2006-12-10)
//		 10, (私有, 可减少重复代码)获取下一个索引的位置, 直至文件尾(2007_3_10) 
//		 11, 现在写数据是写在现有项的后面, 原来的是写在现有项的前面(2007_3_10)
//		 12, 使用const(2007_3_26)
//		 13, 读写Float类型的Vec2D和Vec3D(2007_3_26)
//		 14, 每个读取操作之后会记录是成功读取还是返回默认值(2007_6_9)
