/**
 * Parses a string of well-formed JSON text.
 *
 * If the input is not well-formed, then behavior is undefined, but it is
 * deterministic and is guaranteed not to modify any object other than its
 * return value.
 *
 * This does not use `eval` so is less likely to have obscure security bugs than
 * json2.js.
 * It is optimized for speed, so is much faster than json_parse.js.
 *
 * This library should be used whenever security is a concern (when JSON may
 * come from an untrusted source), speed is a concern, and erroring on malformed
 * JSON is *not* a concern.
 *
 *                      Pros                   Cons
 *                    +-----------------------+-----------------------+
 * json_sans_eval.js  | Fast, secure          | Not validating        |
 *                    +-----------------------+-----------------------+
 * json_parse.js      | Validating, secure    | Slow                  |

 * json2.js           | Fast, some validation | Potentially insecure  |
 *                    +-----------------------+-----------------------+
 *
 * json2.js is very fast, but potentially insecure since it calls `eval` to
 * parse JSON data, so an attacker might be able to supply strange JS that
 * looks like JSON, but that executes arbitrary javascript.
 * If you do have to use json2.js with untrusted data, make sure you keep
 * your version of json2.js up to date so that you get patches as they're
 * released.
 *
 * @param {string} json per RFC 4627
 * @param {function} opt_reviver optional function that reworks JSON objects
 *     post-parse per Chapter 15.12 of EcmaScript3.1.
 *     If supplied, the function is called with a string key, and a value.
 *     The value is the property of 'this'.  The reviver should return
 *     the value to use in its place.  So if dates were serialized as
 *     {@code { "type": "Date", "time": 1234 }}, then a reviver might look like
 *     {@code
 *     function (key, value) {
 *       if (value && typeof value === 'object' && 'Date' === value.type) {
 *         return new Date(value.time);
 *       } else {
 *         return value;
 *       }
 *     }}.
 *     If the reviver returns {@code undefined} then the property named by key
 *     will be deleted from its container.
 *     {@code this} is bound to the object containing the specified property.
 * @return {Object|Array}

    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 object holding the key.

            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) {

        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' &&
                        value.slice(0, 5) === 'Date(' &&
                        value.slice(-1) === ')') {

                    if (d) {

                    }

 *     really sent. Allows for last-minute changes to the URL via setURL(), and

 *
 *   req.url - the full URL as was specified. consider this read-only!
 *     instead of setting req.url, call req.setURL() if you need to make
 *     changes to the URL.
 *
 *   req.useJSONP - set to true to use JSONP, a security hack to allow accessing
 *     a REST resource on a different server than what served this JS file. This
 *     currently ONLY works on a development server, because with JSONP
 *     all requests are GET. We have to consider the security and performance
 *     implications of changing that, but probably it is needed for 3rd party
 *     widgets.
 *
 *   req.isSynchronous - set to true to ensure that this request is not
 *     sent before all previous ones were handled. this way, a certain order
 *     of handling and sending requests is enforced, at a potential performance
 *     penalty.
 *
