** various aspects of the generated parser.
**    YYCODETYPE         is the data type used to store the integer codes
**                       that represent terminal and non-terminal symbols.
**                       "unsigned char" is used if there are fewer than
**                       256 symbols.  Larger types otherwise.
**    YYNOCODE           is a number of type YYCODETYPE that is not used for
**                       any terminal or nonterminal symbol.
**    YYFALLBACK         If defined, this indicates that one or more tokens
**                       (also known as: "terminal symbols") have fall-back
**                       values which should be used if the original symbol
**                       would not parse.  This permits keywords to sometimes
**                       be used as identifiers, for example.
**    YYACTIONTYPE       is the data type used for "action codes" - numbers
**                       that indicate what to do in response to the next
**                       token.
**    TrigParseTOKENTYPE     is the data type used for minor type for terminal
**                       symbols.  Background: A "minor type" is a semantic
**                       value associated with a terminal or non-terminal
**                       symbols.  For example, for an "ID" terminal symbol,
**                       the minor type might be the name of the identifier.
**                       Each non-terminal can have a different minor type.
**                       Terminal symbols all have the same minor type, though.
**                       This macros defines the minor type for terminal 
**                       symbols.
**    YYMINORTYPE        is the data type used for all minor types.
**                       This is typically a union of many types, one of
**                       which is TrigParseTOKENTYPE.  The entry in the union
**                       for terminal symbols is called "yy0".
**    YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
**                       zero the stack is dynamically sized using realloc()
**    TrigParseARG_SDECL     A static variable declaration for the %extra_argument
**    TrigParseARG_PDECL     A parameter declaration for the %extra_argument
**    TrigParseARG_PARAM     Code to pass %extra_argument as a subroutine parameter
**    TrigParseARG_STORE     Code to store %extra_argument into yypParser
**    TrigParseARG_FETCH     Code to extract %extra_argument from yypParser
**    TrigParseCTX_*         As TrigParseARG_ except for %extra_context
**    YYERRORSYMBOL      is the code number of the error symbol.  If not
**                       defined, then do no error processing.
**    YYNSTATE           the combined number of states.
**    YYNRULE            the number of rules in the grammar
**    YYNTOKEN           Number of terminal symbols
**    YY_MAX_SHIFT       Maximum value for shift actions
**    YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions
**    YY_MAX_SHIFTREDUCE Maximum value for shift-reduce actions
**    YY_ERROR_ACTION    The yy_action[] code for syntax error
**    YY_ACCEPT_ACTION   The yy_action[] code for accept
**    YY_NO_ACTION       The yy_action[] code for no-op
**    YY_MIN_REDUCE      Minimum value for reduce actions
**    YY_MAX_REDUCE      Maximum value for reduce actions

/* Next are the 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 <= YY_MAX_SHIFT             Shift N.  That is, push the lookahead
**                                      token onto the stack and goto state N.
**
**   N between YY_MIN_SHIFTREDUCE       Shift to an arbitrary state then
**     and YY_MAX_SHIFTREDUCE           reduce by rule N-YY_MIN_SHIFTREDUCE.
**
**   N == YY_ERROR_ACTION               A syntax error has occurred.
**
**   N == YY_ACCEPT_ACTION              The parser accepts its input.
**
**   N == YY_NO_ACTION                  No such action.  Denotes unused
**                                      slots in the yy_action[] table.
**
**   N between YY_MIN_REDUCE            Reduce by rule N-YY_MIN_REDUCE
**     and YY_MAX_REDUCE
**
** The action table is constructed as a single large table named yy_action[].
** Given state S and lookahead X, the action is computed as either:
**
**    (A)   N = yy_action[ yy_shift_ofst[S] + X ]
**    (B)   N = yy_default[S]
**
** The (A) formula is preferred.  The B formula is used instead if
** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X.
**
** The formulas above are 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 yy_reduce_ofst[] array is used in place of
** the yy_shift_ofst[] array.
**
** The following are the tables generated in this section:
**
**  yy_action[]        A single table containing all actions.
**  yy_lookahead[]     A table containing the lookahead for each entry in
**                     yy_action.  Used to detect hash collisions.
**  yy_shift_ofst[]    For each state, the offset into yy_action for
**                     shifting terminals.
**  yy_reduce_ofst[]   For each state, the offset into yy_action for
**                     shifting non-terminals after a reduce.
**  yy_default[]       Default action for each state.
