/// Rename an existing symbol
///
/// Rename an existing symbol in an integer symbol table.
///
/// # Required Reading
///
/// * [SYMBOLS](crate::required_reading::symbols)
///
/// # Brief I/O
///
/// ```text
///  VARIABLE  I/O  DESCRIPTION
///  --------  ---  --------------------------------------------------
///  OLD        I   Name of the symbol to be renamed.
///  NEW        I   New name of the symbol.
///  TABSYM,
///  TABPTR,
///  TABVAL    I-O  Components of the symbol table.
/// ```
///
/// # Detailed Input
///
/// ```text
///  OLD      is the name of the symbol to be renamed. If OLD is
///           not in the symbol table, the tables are not modified.
///
///  NEW      is the new name of the symbol. If the symbol NEW
///           already exists in the symbol table, it is deleted.
///           OLD is then renamed to NEW.
///
///  TABSYM,
///  TABPTR,
///  TABVAL   are components of the integer symbol table.
/// ```
///
/// # Detailed Output
///
/// ```text
///  TABSYM,
///  TABPTR,
///  TABVAL   are components of the integer symbol table.
///           The values previously associated with OLD are now
///           associated with NEW. If OLD is not in the symbol
///           table, the symbol tables are not modified.
/// ```
///
/// # Exceptions
///
/// ```text
///  1)  If the symbol OLD is not in the symbol table, the error
///      SPICE(NOSUCHSYMBOL) is signaled.
/// ```
///
/// # Examples
///
/// ```text
///  The contents of the symbol table are:
///
///     books   -->   5
///                  10
///     erasers -->   6
///     pencils -->  12
///                  18
///     pens    -->  10
///                  12
///                  24
///
///  The call,
///
///  CALL SYRENI ( 'pens', 'desks', TABSYM, TABPTR, TABVAL )
///
///  modifies the contents of the symbol table to be:
///
///     books   -->   5
///                  10
///     desks   -->  10
///                  12
///                  24
///     erasers -->   6
///     pencils -->  12
///                  18
///
///
///  The next call,
///
///  CALL SYRENI ( 'erasers', 'desks', TABSYM, TABPTR, TABVAL )
///
///  modifies the contents fo the symbol table to be:
///
///     books   -->   5
///                  10
///     desks   -->   6
///     pencils -->  12
///                  18
///
///  Note that the symbol "desks" was deleted from the table,
///  and the symbol "erasers" was then renamed to "STRASSMAN". If the
///  new symbol exists, it is deleted from the table before its name
///  is given to another symbol.
///
///
///  The next call,
///
///  CALL SYRENI ( 'chairs', 'stools', TABSYM, TABPTR, TABVAL )
///
///  does not modify the contents of the symbol table. However, it
///  does signal the error SPICE(NOSUCHSYMBOL) because the symbol
///  "chairs" does not exist in the symbol table.
