//! \class PILog pilog.h
//! \details
//! \~english \section PILog_sec0 Synopsis
//! \~russian \section PILog_sec0 Краткий обзор
//! \~english
//! This class provide handy parsing of command-line arguments. First you should add
//! arguments to %PICLI with function \a addArgument(). Then you can check if there
//! is some argument in application command-line with function \a hasArgument(),
//! or obtain argument value by \a argumentValue().
//!
//! \~russian
//! Этот класс предоставляет удобный механизм для разбора аргументов командной строки.
//! Сперва необходимо добавить аргументы в %PICLI с помощью методов \a addArgument().
//! Далее можно проверять аргументы на наличие в командной строке методом \a hasArgument(),
//! а также получать их значения при помощи \a argumentValue().
//!
//! \~english \section PICLI_sec1 Example
//! \~russian \section PICLI_sec1 Пример
//! \~\code
//! int main(int argc, char ** argv) {
//! 	PICLI cli(argc, argv);
//! 	cli.addArgument("console");
//! 	cli.addArgument("debug");
//! 	cli.addArgument("Value", "v", "value", true);
//! 	if (cli.hasArgument("console"))
//! 		piCout << "console active";
//! 	if (cli.hasArgument("debug"))
//! 		piCout << "debug active";
//! 	piCout << "Value =" << cli.argumentValue("Value");
//! 	return 0;
//! }
//! \endcode
//!
//! \~english These executions are similar:
//! \~russian Эти вызовы будут идентичны:
//!
//! \~\code
//! a.out -cd -v 10
//! a.out --value 10 -dc
//! a.out -c -v 10 -d
//! a.out --console -d -v 10
//! a.out --debug -c --value 10
//! \endcode
