Shows how to use format xtd::parse<bool> method with boolean values.

  console::write_line(b3);
  auto b4 = xtd::parse<bool>("FALSE");
  console::write_line(b4);

  console::write_line(b5);

  console::write_line(b6);

  auto b8 = xtd::parse<bool>("   fAlSe  ");
  console::write_line(b8);

    console::write_line(b9);
  } catch (const system_exception& e) {
