* 将Trace信息输出到chrome浏览器的控制器，从而不影响ajax效果和页面的布局。
* 使用前，你需要先安装 chrome log 这个插件： http://craig.is/writing/chrome-logger。
* 定义应用的tags.php文件 Application/Common/Conf/tags.php，
*
* array(
* 'Behavior\ChromeShowPageTrace'

*
* 如果trace信息没有正常输出，请查看您的日志。
* 这是通过http headers和chrome通信，所以要保证在输出trace信息之前不能有
* headers输出，你可以在入口文件第一行加入代码 ob_start(); 或者配置output_buffering
