/// Sum of an integer array
///
/// Return the sum of the elements of an integer array.
///
/// # Brief I/O
///
/// ```text
/// VARIABLE I/O DESCRIPTION
/// -------- --- --------------------------------------------------
/// ARRAY I Input array.
/// N I Number of elements in ARRAY.
///
/// The function returns the sum of the elements of ARRAY.
/// ```
///
/// # Detailed Input
///
/// ```text
/// ARRAY is the input integer array.
///
/// N is the number of elements in the array.
/// ```
///
/// # Detailed Output
///
/// ```text
/// The function returns the sum of the elements of the input array.
/// That is,
///
/// SUMAI( ARRAY, N ) = ARRAY(1) + ARRAY(2) + ... + ARRAY(N)
///
/// If N is zero or negative, SUMAI is zero.
/// ```
///
/// # Exceptions
///
/// ```text
/// Error free.
/// ```
///
/// # Particulars
///
/// ```text
/// The value of the function is initially set to zero. The elements
/// of the array are then added. If the number of elements is zero or
/// negative, SUMAI is zero.
/// ```
///
/// # Examples
///
/// ```text
/// Let ARRAY contain the following elements.
///
/// ARRAY(1) = 12
/// ARRAY(2) = 1
/// ARRAY(3) = 4
/// ARRAY(4) = 75
/// ARRAY(5) = 18
///
/// Then
///
/// SUMAI ( ARRAY, -3 ) = 0
/// SUMAI ( ARRAY, 0 ) = 0
/// SUMAI ( ARRAY, 1 ) = 12
/// SUMAI ( ARRAY, 2 ) = 13
/// SUMAI ( ARRAY, 5 ) = 110
/// SUMAI ( ARRAY(3), 3 ) = 97
/// ```
///
/// # Restrictions
///
/// ```text
/// 1) SUMAI does not check for overflow.
/// ```
///
/// # Author and Institution

/// J. Diaz del Rio (ODC Space)
/// W.L. Taber (JPL)
/// I.M. Underwood (JPL)

/// # Version
