    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 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()
            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.

// We split the first stage into 4 regexp operations in order to work around
// 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.

// JavaScript structure. The '{' operator is subject to a syntactic ambiguity
// in JavaScript: it can begin a block or an object literal. We wrap the text
// in parens to eliminate the ambiguity.

                    j = eval('(' + text + ')');

// In the optional third stage, we recursively walk the new structure, passing
// each name/value pair to a filter function for possible transformation.

/**
 * The bgiframe is chainable and applies the iframe hack to get 
 * around zIndex issues in IE6. It will only apply itself in IE 
 * and adds a class to the iframe called 'bgiframe'. The iframe
 * is appeneded as the first child of the matched element(s) 
 * with a tabIndex and zIndex of -1.
 * 
 * By default the plugin will take borders, sized with pixel units,
 * into account. If a different unit is used for the border's width,
 * then you will need to use the top and left settings as explained below.
 *
 * NOTICE: This plugin has been reported to cause perfromance problems
 * when used on elements that change properties (like width, height and
 * opacity) a lot in IE6. Most of these problems have been caused by 
 * the expressions used to calculate the elements width, height and 
 * borders. Some have reported it is due to the opacity filter. All 
 * these settings can be changed if needed as explained below.
 *
 * @example $('div').bgiframe();
 * @before <div><p>Paragraph</p></div>
 * @result <div><iframe class="bgiframe".../><p>Paragraph</p></div>
 *
 * @param Map settings Optional settings to configure the iframe.
 * @option String|Number top The iframe must be offset to the top
 * 		by the width of the top border. This should be a negative 
 *      number representing the border-top-width. If a number is 
 * 		is used here, pixels will be assumed. Otherwise, be sure
 *		to specify a unit. An expression could also be used. 
 * 		By default the value is "auto" which will use an expression 
 * 		to get the border-top-width if it is in pixels.
 * @option String|Number left The iframe must be offset to the left
 * 		by the width of the left border. This should be a negative 
 *      number representing the border-left-width. If a number is 
 * 		is used here, pixels will be assumed. Otherwise, be sure
 *		to specify a unit. An expression could also be used. 
 * 		By default the value is "auto" which will use an expression 
 * 		to get the border-left-width if it is in pixels.
 * @option String|Number width This is the width of the iframe. If
 *		a number is used here, pixels will be assume. Otherwise, be sure
 * 		to specify a unit. An experssion could also be used.
 *		By default the value is "auto" which will use an experssion
 * 		to get the offsetWidth.
 * @option String|Number height This is the height of the iframe. If
 *		a number is used here, pixels will be assume. Otherwise, be sure
 * 		to specify a unit. An experssion could also be used.
 *		By default the value is "auto" which will use an experssion
 * 		to get the offsetHeight.
 * @option Boolean opacity This is a boolean representing whether or not
 * 		to use opacity. If set to true, the opacity of 0 is applied. If
 *		set to false, the opacity filter is not applied. Default: true.
 * @option String src This setting is provided so that one could change 
 *		the src of the iframe to whatever they need.
 *		Default: "javascript:false;"
