    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 ' '),
                        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) {
                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' &&
                        value.slice(0, 5) === 'Date(' &&
                        value.slice(-1) === ')') {
                    d = new Date(value.slice(5, -1));
                    if (d) {
                        return d;
                    }
                }

/*
	SWFUpload.SWFObject Plugin

	Summary:
		This plugin uses SWFObject to embed SWFUpload dynamically in the page.  SWFObject provides accurate Flash Player detection and DOM Ready loading.
		This plugin replaces the Graceful Degradation plugin.

	Features:
		* swfupload_load_failed_hander event
		* swfupload_pre_load_handler event
		* minimum_flash_version setting (default: "9.0.28")
		* SWFUpload.onload event for early loading

	Usage:
		Provide handlers and settings as needed.  When using the SWFUpload.SWFObject plugin you should initialize SWFUploading
		in SWFUpload.onload rather than in window.onload.  When initialized this way SWFUpload can load earlier preventing the UI flicker
		that was seen using the Graceful Degradation plugin.

		<script type="text/javascript">
			var swfu;
			SWFUpload.onload = function () {
				swfu = new SWFUpload({
					minimum_flash_version: "9.0.28",
					swfupload_pre_load_handler: swfuploadPreLoad,
					swfupload_load_failed_handler: swfuploadLoadFailed
				});
			};
		</script>
		
	Notes:
		You must provide set minimum_flash_version setting to "8" if you are using SWFUpload for Flash Player 8.
		The swfuploadLoadFailed event is only fired if the minimum version of Flash Player is not met.  Other issues such as missing SWF files, browser bugs
		 or corrupt Flash Player installations will not trigger this event.
		The swfuploadPreLoad event is fired as soon as the minimum version of Flash Player is found.  It does not wait for SWFUpload to load and can
		 be used to prepare the SWFUploadUI and hide alternate content.
		swfobject's onDomReady event is cross-browser safe but will default to the window.onload event when DOMReady is not supported by the browser.
		 Early DOM Loading is supported in major modern browsers but cannot be guaranteed for every browser ever made.
