/**
 * 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.
