-
-
-    This file creates a global JSON object containing two methods: stringify
-    and parse.
-
-        JSON.stringify(value, replacer, space)
-            value       any JavaScript value, usually an object or array.
-
-            replacer    an optional parameter that determines how object
-                        values are stringified for objects. It can be a
-                        function or an array of strings.
-
-            space       an optional parameter that specifies the indentation
-                        of nested structures. If it is omitted, the text will
-                        be packed without extra whitespace. If it is a number,
-                        it will specify the number of spaces to indent at each
-                        level. If it is a string (such as '\t' or '&nbsp;'),
-                        it contains the characters used to indent at each level.
-
-            This method produces a JSON text from a JavaScript value.
-
-            When an object value is found, if the object contains a toJSON
-            method, its toJSON method will be called and the result will be
-            stringified. A toJSON method does not serialize: it returns the
-            value represented by the name/value pair that should be serialized,
-            or undefined if nothing should be serialized. The toJSON method
-            will be passed the key associated with the value, and this will be
-            bound to the value
-
-            For example, this would serialize Dates as ISO strings.
-
-                Date.prototype.toJSON = function (key) {
-                    function f(n) {
-                        // Format integers to have at least two digits.
-                        return n < 10 ? '0' + n : n;
-                    }
-
-                    return this.getUTCFullYear()   + '-' +
-                         f(this.getUTCMonth() + 1) + '-' +
-                         f(this.getUTCDate())      + 'T' +
-                         f(this.getUTCHours())     + ':' +
-                         f(this.getUTCMinutes())   + ':' +
-                         f(this.getUTCSeconds())   + 'Z';
-                };
-
-            You can provide an optional replacer method. It will be passed the
-            key and value of each member, with this bound to the containing
-            object. The value that is returned from your method will be
-            serialized. If your method returns undefined, then the member will
-            be excluded from the serialization.
-
-            If the replacer parameter is an array of strings, then it will be
-            used to select the members to be serialized. It filters the results
-            such that only members with keys listed in the replacer array are
-            stringified.
-
-            Values that do not have JSON representations, such as undefined or
-            functions, will not be serialized. Such values in objects will be
-            dropped; in arrays they will be replaced with null. You can use
-            a replacer function to replace those with JSON values.
-            JSON.stringify(undefined) returns undefined.
-
-            The optional space parameter produces a stringification of the
-            value that is filled with line breaks and indentation to make it
-            easier to read.
-
-            If the space parameter is a non-empty string, then that string will
-            be used for indentation. If the space parameter is a number, then
-            the indentation will be that many spaces.
-
-            Example:
-
-            text = JSON.stringify(['e', {pluribus: 'unum'}]);
-            // text is '["e",{"pluribus":"unum"}]'
-
-
-            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
-            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
-
-            text = JSON.stringify([new Date()], function (key, value) {
-                return this[key] instanceof Date ?
-                    'Date(' + this[key] + ')' : value;
-            });
-            // text is '["Date(---current time---)"]'
-
-
-        JSON.parse(text, reviver)
-            This method parses a JSON text to produce an object or array.
-            It can throw a SyntaxError exception.
-
-            The optional reviver parameter is a function that can filter and
-            transform the results. It receives each of the keys and values,
-            and its return value is used instead of the original value.
-            If it returns what it received, then the structure is not modified.
-            If it returns undefined then the member is deleted.
-
-            Example:
-
-            // Parse the text. Values that look like ISO date strings will
-            // be converted to Date objects.
-
-            myData = JSON.parse(text, function (key, value) {
-                var a;
-                if (typeof value === 'string') {
-                    a =
-/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
-                    if (a) {
-                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
-                            +a[5], +a[6]));
-                    }
-                }
-                return value;
-            });
-
-            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
-                var d;
-                if (typeof value === 'string' &&
