///  Fundamental argument, IERS Conventions (2003):

///  Given:
///   * t TDB, Julian centuries since J2000.0 (Note 1)
///
///  Returned (function value):
///     * mean longitude of Mars, radians (Note 2)
///
/// # Notes:
///
///  1) Though t is strictly TDB, it is usually more convenient to use
///     TT, which makes no significant difference.
///
///  2) The expression used is as adopted in IERS Conventions (2003) and
///     comes from Souchay et al. (1999) after Simon et al. (1994).
