* TLogRouter class.

* TLogRouter manages routes that record log messages in different media different ways.
* For example, a file log route {@link TFileLogRoute} records log messages
* in log files. An email log route {@link TEmailLogRoute} sends log messages
* to email addresses.
*
* Log routes may be configured in application or page folder configuration files
* or an external configuration file specified by {@link setConfigFile ConfigFile}.
* The format is as follows,
* <code>
* <route class="TFileLogRoute" Categories="System.Web.UI" Levels="Warning" />
* <route class="TEmailLogRoute" Categories="Application" Levels="Fatal" Emails="admin@pradosoft.com" />
* </code>
* PHP configuration style:
* <code>
*
* </code>
* You can specify multiple routes with different filtering conditions and different
* targets, even if the routes are of the same type.
