/// # Brief I/O
///
/// ```text
///  VARIABLE  I/O  DESCRIPTION
///  --------  ---  --------------------------------------------------
///  HANDLE     I   EK file handle.
///  SEGNO      I   Index of segment containing record.
///  RECNO      I   Record to which data is to be added.
///  COLUMN     I   Column name.
///  NVALS      I   Number of values to add to column.
///  CVALS      I   Character values to add to column.
///  ISNULL     I   Flag indicating whether column entry is null.
/// ```
///
/// # Detailed Input
///
/// ```text
///  HANDLE   is the handle of an EK file open for write access.
///
///  SEGNO    is the index of the segment to which data is to
///           be added.
///
///  RECNO    is the index of the record to which data is to be
///           added. This record number is relative to the start
///           of the segment indicated by SEGNO; the first
///           record in the segment has index 1.
///
///  COLUMN   is the name of the column to which data is to be
///           added.
///
///  NVALS,
///  CVALS    are, respectively, the number of values to add to
///           the specified column and the set of values
///           themselves. The data values are written into the
///           specified column and record.
///
///           If the  column has fixed-size entries, then NVALS
///           must equal the entry size for the specified column.
///
///           Only one value can be added to a virtual column.
///
///
///  ISNULL   is a logical flag indicating whether the entry is
///           null. If ISNULL is .FALSE., the column entry
///           defined by NVALS and CVALS is added to the
///           specified kernel file.
///
///           If ISNULL is .TRUE., NVALS and CVALS are ignored.
///           The contents of the column entry are undefined.
///           If the column has fixed-length, variable-size
///           entries, the number of entries is considered to
///           be 1.
/// ```
///
/// # Detailed Output
///
/// ```text
///  None. See $Particulars for a description of the effect of this
///  routine.
/// ```
///
/// # Exceptions
///
/// ```text
///  1)  If HANDLE is invalid, an error is signaled by a routine in the
///      call tree of this routine.
///
///  2)  If SEGNO is out of range, an error is signaled by a routine in
///      the call tree of this routine.
///
///  3)  If COLUMN is not the name of a declared column, an error
///      is signaled by a routine in the call tree of this routine.
///
///  4)  If COLUMN specifies a column of whose data type is not
///      character, the error SPICE(WRONGDATATYPE) is signaled.
///
///  5)  If RECNO is out of range, an error is signaled by a routine in
///      the call tree of this routine.
///
///  6)  If the specified column has fixed-size entries and NVALS does
///      not match this size, an error is signaled by a routine in the
///      call tree of this routine.
///
///  7)  If the specified column has variable-size entries and NVALS is
///      non-positive, an error is signaled by a routine in the call
///      tree of this routine.
///
///  8)  If an attempt is made to add a null value to a column that
///      doesn't take null values, an error is signaled by a routine in
///      the call tree of this routine.
///
///  9)  If COLUMN specifies a column of whose class is not
///      an character class known to this routine, the error
///      SPICE(NOCLASS) is signaled.
///
///  10) If an I/O error occurs while reading or writing the indicated
///      file, the error is signaled by a routine in the call tree of
///      this routine.

/// # Particulars
///
/// ```text
///  This routine operates by side effects: it modifies the named
///  EK file by adding data to the specified record in the specified
///  column. Data may be added to a segment in random order; it is not
///  necessary to fill in columns or rows sequentially. Data may only
///  be added one column entry at a time.
/// ```

/// # Examples

///  The numerical results shown for these examples 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.

///           ORDER_DATE      TIME
///           COST            DOUBLE PRECISION
///
///     The order database also has a table of items that have been
///     ordered. The columns of this table are shown below:
///
///        DATAITEMS
///
///           Column Name     Data Type
///           -----------     ---------
///           ITEM_ID         INTEGER

///           PRICE           DOUBLE PRECISION
///
///
///     We'll suppose that the EK file contains two segments, the

///     containing the DATAITEMS table.
///
///     This examples demonstrates how to open a new EK file; create
