Header files are now always included with their path from the
project's root directory rather than the path relative to
the includer.

+/**
+ * @brief Log formatter for Boost.Test that outputs the logging to multiple formatters
+ *
+ * The log formatter is designed to output to one or multiple formatters at the same time.  For
+ * example, one HRF formatter can output to the standard output, while XML formatter output to
+ * the file.
+ *
+ * Usage:
+ *
+ *     // Call in init_unit_test_suite: (this will override the --log_format parameter)
+ *     auto formatter = new boost::unit_test::output::multi_log_formatter; // same as already configured logger
+ *
+ *     // Prepare and add additional logger(s)
+ *     formatter.add(std::make_shared<boost::unit_test::output::xml_log_formatter>(),
+ *                   std::make_shared<std::ofstream>("out.xml"));
+ *
+ *      boost::unit_test::unit_test_log.set_formatter(formatter);
+ *
+ * @note Calling `boost::unit_test::unit_test_log.set_stream(...)` will change the stream for
+ *       the original logger.
