/// Negate a double precision 3-dimensional vector.
///
/// # Brief I/O
///
/// ```text
/// VARIABLE I/O DESCRIPTION
/// -------- --- --------------------------------------------------
/// V1 I Vector to be negated.
/// VOUT O Negated vector -V1.
/// ```
///
/// # Detailed Input
///
/// ```text
/// V1 is any double precision 3-dimensional vector.
/// ```
///
/// # Detailed Output
///
/// ```text
/// VOUT is the negation (additive inverse) of V1. It is a
/// double precision 3-dimensional vector.
/// ```
///
/// # Exceptions
///
/// ```text
/// Error free.
/// ```
///
/// # Particulars
///
/// ```text
/// For each value of the index I from 1 to 3, VMINUS negates V1
/// by the expression:
///
/// VOUT(I) = - V1(I)
///
/// No error checking is performed since overflow can occur ONLY if
/// the dynamic range of positive floating point numbers is not the
/// same size as the dynamic range of negative floating point numbers
/// AND at least one component of V1 falls outside the common range.
/// The likelihood of this occurring is so small as to be of no
/// concern.
/// ```
///
/// # Examples
///
/// ```text
/// The numerical results shown for this example may differ across
/// platforms. The results depend on the SPICE kernels used as
/// input, the compiler and supporting libraries, and the machine
/// specific arithmetic implementation.
///
