	\brief Средство для определения размера двоичного
	представления объекта указанного типа.

	Пример использования:
	\code
	int char_size = oess_1::io::bin_data_size_t< oess_1::char_t >::image_size;
	int int_size = oess_1::io::bin_data_size_t< oess_1::int_t >::image_size;
	int double_size = oess_1::io::bin_data_size_t< oess_1::double_t >::image_size;
	\endcode

	\attention
	Определяет корректный размер только для oess_1::char_t,
	oess_1::schar_t, oess_1::uchar_t, oess_1::short_t, oess_1::ushort_t,
	oess_1::int_t, oess_1::uint_t, oess_1::single_t, oess_1::double_t.
