    This file creates a global JSON object containing two methods:

        JSON.stringify(value, whitelist)
            value       any JavaScript value, usually an object or array.

            whitelist   an optional array prameter that determines how object
                        values are stringified.

            This method produces a JSON text from a JavaScript value.
            There are three possible ways to stringify an object, depending
            on the optional whitelist parameter.

            If an object has a toJSON method, then the toJSON() method will be
            called. The value returned from the toJSON method will be
            stringified.

            Otherwise, if the optional whitelist parameter is an array, then
            the elements of the array will be used to select members of the
            object for stringification.

            Otherwise, if there is no whitelist parameter, then all of the
            members of the object will be stringified.

            Values that do not have JSON representaions, such as undefined or
            functions, will not be serialized. Such values in objects will be
            dropped; in arrays will be replaced with null.
            JSON.stringify(undefined) returns undefined. Dates will be
            stringified as quoted ISO dates.

            Example:

            var text = JSON.stringify(['e', {pluribus: 'unum'}]);
            // text is '["e",{"pluribus":"unum"}]'

        JSON.parse(text, filter)
            This method parses a JSON text to produce an object or
            array. It can throw a SyntaxError exception.

            The optional filter 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 structure is not modified. If it
            returns undefined then the member is deleted.

            Example:

            // Parse the text. If a key contains the string 'date' then
            // convert the value to a date.

            myData = JSON.parse(text, function (key, value) {
                return key.indexOf('date') >= 0 ? new Date(value) : value;
            });

    This is a reference implementation. You are free to copy, modify, or
    redistribute.

    Use your own copy. It is extremely unwise to load third party
    code into your pages.

// unexpected forms.

// crippling inefficiencies in IE's and Safari's regexp engines. First we
// replace all backslash pairs with '@' (a non-JSON character). Second, we
// replace all simple value tokens with ']' characters. Third, we delete all
// open brackets that follow a colon or comma or that begin the text. Finally,
// we look to see that the remaining characters are only whitespace or ']' or
// ',' or ':' or '{' or '}'. If that is so, then the text is safe for eval.

// in JavaScript: it can begin a block or an object literal. We wrap the text
// in parens to eliminate the ambiguity.
