/* Next are that tables used to determine what action to take based on the
** current state and lookahead token.  These tables are used to implement
** functions that take a state number and lookahead value and return an
** action integer.  
**
** Suppose the action integer is N.  Then the action is determined as
** follows
**
**   0 <= N < self::YYNSTATE                              Shift N.  That is,
**                                                        push the lookahead
**                                                        token onto the stack
**                                                        and goto state N.
**
**   self::YYNSTATE <= N < self::YYNSTATE+self::YYNRULE   Reduce by rule N-YYNSTATE.
**
**   N == self::YYNSTATE+self::YYNRULE                    A syntax error has occurred.
**
**   N == self::YYNSTATE+self::YYNRULE+1                  The parser accepts its
**                                                        input. (and concludes parsing)
**
**   N == self::YYNSTATE+self::YYNRULE+2                  No such action.  Denotes unused
**                                                        slots in the yy_action[] table.
**
** The action table is constructed as a single large static array $yy_action.
** Given state S and lookahead X, the action is computed as
**
**      self::$yy_action[self::$yy_shift_ofst[S] + X ]
**
** If the index value self::$yy_shift_ofst[S]+X is out of range or if the value
** self::$yy_lookahead[self::$yy_shift_ofst[S]+X] is not equal to X or if
** self::$yy_shift_ofst[S] is equal to self::YY_SHIFT_USE_DFLT, it means that
** the action is not in the table and that self::$yy_default[S] should be used instead.  
**
** The formula above is for computing the action when the lookahead is
** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
** a reduce action) then the static $yy_reduce_ofst array is used in place of
** the static $yy_shift_ofst array and self::YY_REDUCE_USE_DFLT is used in place of
** self::YY_SHIFT_USE_DFLT.
**
** The following are the tables generated in this section:
**
**  self::$yy_action        A single table containing all actions.
**  self::$yy_lookahead     A table containing the lookahead for each entry in
**                          yy_action.  Used to detect hash collisions.
**  self::$yy_shift_ofst    For each state, the offset into self::$yy_action for
**                          shifting terminals.
**  self::$yy_reduce_ofst   For each state, the offset into self::$yy_action for
**                          shifting non-terminals after a reduce.
**  self::$yy_default       Default action for each state.
