* \brief Basic logger class
*
* The \c basic_logger class template serves as a base class for all loggers
* provided by the library. It can also be used as a base for user-defined
* loggers. The template parameters are:
*
* \li \c CharT - logging character type
* \li \c FinalT - final type of the logger that eventually derives from
* the \c basic_logger. There may be other classes in the hierarchy
* between the final class and \c basic_logger.
* \li \c ThreadingModelT - threading model policy. Must provide methods
* of the Boost.Thread locking concept used in \c basic_logger class
* and all its derivatives in the hierarchy up to the \c FinalT class.
* The \c basic_logger class itself requires methods of the
* SharedLockable concept. The threading model policy must also be
* default and copy-constructible and support member function \c swap.
* There are currently two policies provided: \c single_thread_model
* and \c multi_thread_model.
*
* The logger implements fundamental facilities of loggers, such as storing
* source-specific attribute set and formatting log record messages. The basic
* logger interacts with the logging core in order to apply filtering and
* pass records to sinks.
