+ * \class AbstractAppender
+ *
+ * \brief The AbstractAppender class provides an abstract base class for writing a log entries.
+ *
+ * The AbstractAppender class is the base interface class for all log appenders that could be used with Logger.
+ *
+ * AbstractAppender provides a common implementation for the thread safe, mutex-protected logging of application
+ * messages, such as ConsoleAppender, FileAppender or something else. AbstractAppender is abstract and can not be
+ * instantiated, but you can use any of its subclasses or create a custom log appender at your choice.
+ *
+ * Appenders are the logical devices that is aimed to be attached to Logger object by calling
+ * Logger::registerAppender(). On each log record call from the application Logger object sequentially calls write()
+ * function on all the appenders registered in it.
+ *
+ * You can subclass AbstractAppender to implement a logging target of any kind you like. It may be the external logging
+ * subsystem (for example, syslog in *nix), XML file, SQL database entries, D-Bus messages or anything else you can
+ * imagine.
+ *
+ * For the simple non-structured plain text logging (for example, to a plain text file or to the console output) you may
+ * like to subclass the AbstractStringAppender instead of AbstractAppender, which will give you a more convinient way to
+ * control the format of the log output.

+/**
+ * The string format seems to be very common to those developers who have used a standart sprintf function.
+ *
+ * Log output format is a simple QString with the special markers (starting with % sign) which will be replaced with
+ * it's internal meaning when writing a log record.
+ *
+ * Controlling marker begins with the percent sign (%) which is followed by the command inside {} brackets
+ * (the command describes, what will be put to log record instead of marker).
+ * Optional field width argument may be specified right after the command (through the colon symbol before the closing bracket)
+ * Some commands requires an additional formatting argument (in the second {} brackets).
+ *
+ * Field width argument works almost identically to the \c QString::arg() \c fieldWidth argument (and uses it
+ * internally). For example, \c "%{type:-7}" will be replaced with the left padded debug level of the message
+ * (\c "Debug  ") or something. For the more detailed description of it you may consider to look to the Qt
+ * Reference Documentation.
+ *
+ * Supported marker commands are:
+ *   \arg \c %{time} - timestamp. You may specify your custom timestamp format using the second {} brackets after the marker,
+ *           timestamp format here will be similiar to those used in QDateTime::toString() function. For example,
+ *           "%{time}{dd-MM-yyyy, HH:mm}" may be replaced with "17-12-2010, 20:17" depending on current date and time.
+ *           The default format used here is "HH:mm:ss.zzz".
+ *   \arg \c %{type} - Log level. Possible log levels are shown in the Logger::LogLevel enumerator.
+ *   \arg \c %{Type} - Uppercased log level.
+ *   \arg \c %{typeOne} - One letter log level.
+ *   \arg \c %{TypeOne} - One uppercase letter log level.
+ *   \arg \c %{File} - Full source file name (with path) of the file that requested log recording. Uses the \c __FILE__
+ *           preprocessor macro.
+ *   \arg \c %{file} - Short file name (with stripped path).
+ *   \arg \c %{line} - Line number in the source file. Uses the \c __LINE__ preprocessor macro.
+ *   \arg \c %{Function} - Name of function that called on of the LOG_* macros. Uses the \c Q_FUNC_INFO macro provided with
+ *           Qt.
+ *   \arg \c %{function} - Similiar to the %{Function}, but the function name is stripped using stripFunctionName
+ *   \arg \c %{message} - The log message sent by the caller.
+ *   \arg \c %{category} - The log category.
+ *   \arg \c %{appname} - Application name (returned by QCoreApplication::applicationName() function).
+ *   \arg \c %{pid} - Application pid (returned by QCoreApplication::applicationPid() function).
+ *   \arg \c %{threadid} - ID of current thread.
+ *   \arg \c %% - Convinient marker that is replaced with the single \c % mark.
+ *
+ * \note Format doesn't add \c '\\n' to the end of the format line. Please consider adding it manually.

+ * \mainpage
+ *
+ * Logger is a simple way to write the history of your application lifecycle to any target logging device (which is
+ * called Appender and may write to any target you will implement with it: console, text file, XML or something - you
+ * choose) and to map logging message to a class, function, source file and line of code which it is called from.
+ *
+ * Some simple appenders (which may be considered an examples) are provided with the Logger itself: see ConsoleAppender
+ * and FileAppender documentation.
+ *
+ * It supports using it in a multithreaded applications, so all of its functions are thread safe.
+ *
+ * Simple usage example:
+ * \code
+ * #include <QCoreApplication>
+ *
+ * #include <Logger.h>
+ * #include <ConsoleAppender.h>
+ *
+ * int main(int argc, char* argv[])
+ * {
+ *   QCoreApplication app(argc, argv);
+ *   ...
+ *   ConsoleAppender* consoleAppender = new ConsoleAppender;
+ *   consoleAppender->setFormat("[%{type:-7}] <%{Function}> %{message}\n");
+ *   cuteLogger->registerAppender(consoleAppender);
+ *   ...
+ *   LOG_INFO("Starting the application");
+ *   int result = app.exec();
+ *   ...
+ *   if (result)
+ *     LOG_WARNING() << "Something went wrong." << "Result code is" << result;
+ *
+ *   return result;
+ * }
+ * \endcode
+ *
+ * Logger internally uses the lazy-initialized singleton object and needs no definite initialization, but you may
+ * consider registering a log appender before calling any log recording functions or macros.
+ *
+ * The library design of Logger allows you to simply mass-replace all occurrences of qDebug and similar calls with
+ * similar Logger macros (e.g. LOG_DEBUG())
+ *
+ * \note Logger uses a singleton global instance which lives through all the application life cycle and self-destroys
+ *       destruction of the QCoreApplication (or QApplication) instance. It needs a QCoreApplication instance to be
+ *       created before any of the Logger's functions are called.
+ *

+ *
+ * This macro is used to pass all log messages inside your custom class to the specific category.
+ * You must include this macro inside your class declaration (similarly to the Q_OBJECT macro).
+ * Internally, this macro redefines cuteLoggerInstance() function, creates the local Logger object inside your class and
+ * sets the default category to the specified parameter.
+ *
+ * Thus, any call to cuteLoggerInstance() (for example, inside LOG_TRACE() macro) will return the local Logger object,
+ * so any logging message will be directed to the default category.
+ *
+ * \note This macro does not register any appender to the newly created logger instance. You should register
+ * logger appenders manually, inside your class.
+ *
+ * Usage example:
+ * \code
+ * class CustomClass : public QObject
+ * {
+ *   Q_OBJECT
+ *   LOG_CATEGORY("custom_category")
+ *   ...
+ * };

+ * }
+ * \endcode
+ *
+ * If used compiler supports C++11 standard, LOG_CATEGORY and LOG_GLOBAL_CATEGORY macros would also work when added
+ * inside of any scope. It could be useful, for example, to log every single run of a method to a different file.
+ *
+ * \code
+ * void foo()
+ * {
+ *   QString categoryName = QDateTime::currentDateTime().toString("yyyy-MM-ddThh-mm-ss-zzz");

+ * preprocessor macros (as the LOG_DEBUG() does) to fill the necessary arguments of the Logger::writeAssert() call. It
+ * also uses undocumented but rather mature and stable \c qt_noop() function (which does nothing) when the assertion
+ * is true.
+ *
+ * Example:
+ * \code
+ * bool b = checkSomething();
+ * ...
+ * LOG_ASSERT(b == true);

+ *
+ * \brief Logs the processing time of current function / code block

+ *   ... // Do some long operations
+ *   return 0;
+ * } // Outputs: Function foo finished in <time> ms.

+ * int bar(bool doFoo)
+ * {
+ *   LOG_TRACE_TIME();
+ *
+ *   if (doFoo)
+ *   {
+ *     LOG_TRACE_TIME("Foo");
