/**
* CLogRoute is the base class for all log route classes.
*
* A log route object retrieves log messages from a logger and sends it
* somewhere, such as files, emails.
* The messages being retrieved may be filtered first before being sent
* to the destination. The filters include log level filter and log category filter.
*
* To specify level filter, set {@link levels} property,
* which takes a string of comma-separated desired level names (e.g. 'Error, Debug').
* To specify category filter, set {@link categories} property,
* which takes a string of comma-separated desired category names (e.g. 'System.Web, System.IO').
*
* Level filter and category filter are combinational, i.e., only messages
* satisfying both filter conditions will they be returned.
