-/* parser generated by jison 0.4.18 */
-/*
-  Returns a Parser object of the following structure:
-
-  Parser: {
-    yy: {}
-  }
-
-  Parser.prototype: {
-    yy: {},
-    trace: function(),
-    symbols_: {associative list: name ==> number},
-    terminals_: {associative list: number ==> name},
-    productions_: [...],
-    performAction: function anonymous(yytext, yyleng, yylineno, yy, yystate, $$, _$),
-    table: [...],
-    defaultActions: {...},
-    parseError: function(str, hash),
-    parse: function(input),
-
-    lexer: {
-        EOF: 1,
-        parseError: function(str, hash),
-        setInput: function(input),
-        input: function(),
-        unput: function(str),
-        more: function(),
-        less: function(n),
-        pastInput: function(),
-        upcomingInput: function(),
-        showPosition: function(),
-        test_match: function(regex_match_array, rule_index),
-        next: function(),
-        lex: function(),
-        begin: function(condition),
-        popState: function(),
-        _currentRules: function(),
-        topState: function(),
-        pushState: function(condition),
-
-        options: {
-            ranges: boolean           (optional: true ==> token location info will include a .range[] member)
-            flex: boolean             (optional: true ==> flex-like lexing behaviour where the rules are tested exhaustively to find the longest match)
-            backtrack_lexer: boolean  (optional: true ==> lexer regexes are tested in order and for each matching regex the action code is invoked; the lexer terminates the scan when a token is returned by the action code)
-        },
-
-        performAction: function(yy, yy_, $avoiding_name_collisions, YY_START),
-        rules: [...],
-        conditions: {associative list: name ==> set},
-    }
-  }
-
-
-  token location info (@$, _$, etc.): {
-    first_line: n,
-    last_line: n,
-    first_column: n,
-    last_column: n,
-    range: [start_number, end_number]       (where the numbers are indexes into the input string, regular zero-based)
-  }
-
-
-  the parseError function receives a 'hash' object with these members for lexer and parser errors: {
-    text:        (matched text)
-    token:       (the produced terminal token, if any)
-    line:        (yylineno)
-  }
-  while parser (grammar) errors will also provide these members, i.e. parser errors deliver a superset of attributes: {
-    loc:         (yylloc)
-    expected:    (string describing the set of expected tokens)
-    recoverable: (boolean: TRUE when the parser has a error recovery rule available for this particular error)
-  }

-    loc:         (yylloc)
-    expected:    (string describing the set of expected tokens)
-    recoverable: (boolean: TRUE when the parser has a error recovery rule available for this particular error)
