  // You can convert to Hexadecimal output rather than Decimal output using Hex.
  // To do this, pass strings::Hex(my_int) as a parameter to StrCat. You may
  // specify a minimum field width using a separate parameter, so the equivalent
  -// of Printf("%04x", my_int) is StrCat(Hex(my_int, strings::ZERO_PAD_4))
