/// Vector addition, 3 dimensional
///
/// Add two double precision 3-dimensional vectors.
///
/// # Brief I/O
///
/// ```text
///  VARIABLE  I/O  DESCRIPTION
///  --------  ---  --------------------------------------------------
///  V1         I   First vector to be added.
///  V2         I   Second vector to be added.
///  VOUT       O   Sum vector, V1 + V2.
/// ```
///
/// # Detailed Input
///
/// ```text
///  V1,
///  V2       are two arbitrary double precision 3-dimensional
///           vectors.
/// ```
///
/// # Detailed Output
///
/// ```text
///  VOUT     is the double precision 3-dimensional vector sum of V1
///           and V2.
/// ```
///
/// # Exceptions
///
/// ```text
///  Error free.
/// ```
///
/// # Particulars
///
/// ```text
///  This routine simply performs addition between components of V1
///  and V2. No checking is performed to determine whether floating
///  point overflow has occurred.
/// ```
///
/// # 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.
///
///  1) Define two sets of 3-dimensional vectors and compute the sum
///     of each vector in first set with the corresponding vector in
