 * 类名：TagHader
 * 功能：实现标签选项卡切换类
 * 编写：陈满意
 * 日期：2008-12-16
 * 使用方法及参数说明：
 *	 var newtags = new TagHader({Index:0,TagIds:"tagA,tagB,tagC",BodyIds:"bodyA,bodyB,bodyC",Styles:"tagFocus,tagBlur"});
 *   Index : 默认切换到的标签下表，从0开始
 *	 TagIds ：所有标签的ID集合
 *	 BodyIds ：显示内容区域的ID集合，应与TagIds对应
 *   Styles ：标签的样式，第一个为标签获取焦点的样式，第二个为标签失去焦点的样式
