/// @brief Manages the sets of loggers, their streams and log levels
///
/// The Boost.Test framework allows for having several formatters/loggers at the same time, each of which
/// having their own log level and output stream.
///
/// This class serves the purpose of
/// - exposing an interface to the test framework (as a boost::unit_test::test_observer)
/// - exposing an interface to the testing tools
/// - managing several loggers
///
/// @note Accesses to the functions exposed by this class are made through the singleton
/// @c boost::unit_test::unit_test_log.
///
/// Users/developers willing to implement their own formatter need to:
/// - implement a boost::unit_test::unit_test_log_formatter that will output the desired format
/// - register the formatter during a eg. global fixture using the method @c set_formatter (though the framework singleton).
///
/// @warning this observer has a higher priority than the @ref boost::unit_test::results_collector_t. This means
/// that the various @ref boost::unit_test::test_results associated to each test unit may not be available at the time
/// the @c test_unit_start, @c test_unit_finish ... are called.
///
/// @see
/// - boost::unit_test::test_observer
/// - boost::unit_test::unit_test_log_formatter

//!
//! The log level and output stream of the new formatter are taken from the currently active logger. In case
//! several loggers are active, the order of priority is CUSTOM, HRF, XML, and JUNIT.
//! If (unit_test_log_formatter*)0 is given as argument, the custom logger (if any) is removed.
//!
//! @note The ownership of the pointer is transfered to the Boost.Test framework. This call is equivalent to

//! the existing one gets replaced by the one given in argument.
//! The provided logger is added with an enabled state.
