[版本记录]
2009-06-01:版本1.0.1发布。
2009-07-05:版本1.0.2,更新了一些明显的BUG,完全支持了IE系列浏览器。
2009-08-15:版本1.0.3,封装了标准DOM,多浏览器下兼容,样式美化,添加了阴影效果。
2009-11-05:版本2.0.0,基于JQuery全新封装,应用了JS的命名空间,避免了客户端id冲突。
            项目正式更名为JQuery Dialog,优化了拖拽的核心实现,完全支持跨浏览器。
2009-12-13:版本2.0.1,优化了核心的拖拽算法,分离出DragAndDrop类。
            使用异步的Javascript让拖拽更为流畅。
            修复了鼠标拖动过快Dialog停顿的BUG。
            对拖拽的位置与滚动条之间进行协调,限制拖拽范围,修复了原有BUG。
            修复了当Dialog宽或高大于页面时定位的BUG。
            修复了鼠标样式与拖拽控制区不精确的BUG。
            至此,完善为一个较为强壮JQuery插件了。
2010-02-03:版本2.0.3,JQuery升级为1.4。
            为Open增加了内部扩展接口。
            修复IE6下部分显示BUG。
