/**
* CLogRouter manages log routes that record log messages in different media.
*
* For example, a file log route {@link CFileLogRoute} records log messages
* in log files. An email log route {@link CEmailLogRoute} sends log messages
* to specific email addresses. See {@link CLogRoute} for more details about
* different log routes.
*
* Log routes may be configured in application configuration like following:
* <pre>
* array(
* 'preload'=>array('log'), // preload log component when app starts
* 'components'=>array(
* 'log'=>array(
* 'class'=>'CLogRouter',
* 'routes'=>array(
* array(
* 'class'=>'CFileLogRoute',
* 'levels'=>'trace, info',
* 'categories'=>'system.*',
* ),
* array(
* 'class'=>'CEmailLogRoute',
* 'levels'=>'error, warning',
* 'emails'=>array('admin@example.com'),
* ),
* ),
* ),
* ),
* )
* </pre>
*
* You can specify multiple routes with different filtering conditions and different
* targets, even if the routes are of the same type.
*
* @property array $routes The currently initialized routes.
