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

 * jGrowl 1.1.2

 *
 * Written by Stan Lemon <stanlemon@mac.com>
 * Last updated: 2008.08.17
 *
 * jGrowl is a jQuery plugin implementing unobtrusive userland notifications.  These 
 * notifications function similarly to the Growl Framework available for
 * Mac OS X (http://growl.info).
 *
 * To Do:
 * - Move library settings to containers and allow them to be changed per container
 *
 * Changes in 1.1.2
 * - Added iPhone styled example
 * - Fixed possible IE7 bug when determining if the ie6 class shoudl be applied.
 * - Added template for the close button, so that it's content could be customized.
 *
 * Changes in 1.1.1
 * - Fixed CSS styling bug for ie6 caused by a mispelling
 * - Changes height restriction on default notifications to min-height
 * - Added skinned examples using a variety of images
 * - Added the ability to customize the content of the [close all] box
 * - Added jTweet, an example of using jGrowl + Twitter
 *
 * Changes in 1.1.0
 * - Multiple container and instances.
 * - Standard $.jGrowl() now wraps $.fn.jGrowl() by first establishing a generic jGrowl container.
 * - Instance methods of a jGrowl container can be called by $.fn.jGrowl(methodName)
 * - Added glue preferenced, which allows notifications to be inserted before or after nodes in the container
 * - Added new log callback which is called before anything is done for the notification
 * - Corner's attribute are now applied on an individual notification basis.
 *
 * Changes in 1.0.4
 * - Various CSS fixes so that jGrowl renders correctly in IE6.
 *
 * Changes in 1.0.3
 * - Fixed bug with options persisting across notifications
 * - Fixed theme application bug
 * - Simplified some selectors and manipulations.
 * - Added beforeOpen and beforeClose callbacks
 * - Reorganized some lines of code to be more readable
 * - Removed unnecessary this.defaults context
 * - If corners plugin is present, it's now customizable.
 * - Customizable open animation.
 * - Customizable close animation.
 * - Customizable animation easing.
 * - Added customizable positioning (top-left, top-right, bottom-left, bottom-right, center)
 *
 * Changes in 1.0.2
 * - All CSS styling is now external.
 * - Added a theme parameter which specifies a secondary class for styling, such
 *   that notifications can be customized in appearance on a per message basis.
 * - Notification life span is now customizable on a per message basis.
 * - Added the ability to disable the global closer, enabled by default.
 * - Added callbacks for when a notification is opened or closed.
 * - Added callback for the global closer.
 * - Customizable animation speed.
 * - jGrowl now set itself up and tears itself down.
 *
 * Changes in 1.0.1:
 * - Removed dependency on metadata plugin in favor of .data()
 * - Namespaced all events

 * Licensed under the MIT:

 *
 * Copyright 2007, 2008 Chris Wanstrath [ chris@ozmm.org ]
 *
 * Usage:
 *  
 *  jQuery(document).ready(function() {
 *    jQuery('a[rel*=facebox]').facebox() 
 *  })
 *
 *  <a href="#terms" rel="facebox">Terms</a>
 *    Loads the #terms div in the box
 *
 *  <a href="terms.html" rel="facebox">Terms</a>
 *    Loads the terms.html page in the box
 *
 *  <a href="terms.png" rel="facebox">Terms</a>
 *    Loads the terms.png image in the box
 *
 *
 *  You can also use it programmatically:
 * 
 *    jQuery.facebox('some html')
 *
 *  The above will open a facebox with "some html" as the content.
 *    
 *    jQuery.facebox(function($) { 
 *      $.get('blah.html', function(data) { $.facebox(data) })
 *    })
 *
 *  The above will show a loading screen before the passed function is called,
 *  allowing for a better ajaxy experience.
 *
 *  The facebox function can also display an ajax page or image:
 *  
 *    jQuery.facebox({ ajax: 'remote.html' })
 *    jQuery.facebox({ image: 'dude.jpg' })
 *
 *  Want to close the facebox?  Trigger the 'close.facebox' document event:
 *
 *    jQuery(document).trigger('close.facebox')
 *
 *  Facebox also has a bunch of other hooks:
 *
 *    loading.facebox
 *    beforeReveal.facebox
 *    reveal.facebox (aliased as 'afterReveal.facebox')
 *    init.facebox
 *
 *  Simply bind a function to any of these hooks:
 *
 *   $(document).bind('reveal.facebox', function() { ...stuff to do after the facebox and contents are revealed... })
 *

   Usage:

   Description:

   The first argument is a hash of named parameters, including:
    - 'actions' is an array of monikers to submit
    - 'action_arguments' is a hash of action monikers to hashes of arguments which should override any arguments coming from form fields
          the hash keys for 'action_arguments' are the values of the 'actions' array
    - 'continuation' is ??? Please document me
    - 'hide_wait_message' for when you don't want to see it
    - 'preload' this request is preloading regions
    - 'preload_key' the cache key for using preloaded regions
    - 'headers' is a hash of headers to send in this request
    - 'fragments' is an array of hashes, which may have:
       - 'region' is the name of the region to update
       - 'args' is a hash of arguments to override
       - 'path' is the path of the fragment (if this is a new fragment)
       - 'element' is the CSS selector of the element to update, if 'region' isn't supplied
       - 'mode' is one of 'Replace', 'Top', 'Bottom', 'Before', or 'After'
       - 'effect' is the name of an effect
  
    The second argument is the element (usually a submit button) that triggered
    it.

 * Jifty.Effect Usage:
 *

 * When called, instantly perform a js effect on give element.
 *
 * The last arg "option" is a hash. Currently it's only used for
 * specifying callbacks. There are two possible callbacks, before
 * and after. You may specify them like this:
 *
 * Jifty.Effect(element, "Fade", { duration: 2.0 }, {
 *     before: function() { ... },
 *     after: function() { ... }
 * });
 *
 * The "before" callback is called right before the effect starts.
 * The "after" callback is called right after it's started, but not
 * necessarily ended.
 *
 * This function is written to make it possible that a Jifty plugin
 * can override default effects with other fancy javascript
 * libraries. By default, it delegates all the real work to
 * jQuery's built-in effect functions.

/**
* Calendar is the base class for the Calendar widget. In its most basic
* implementation, it has the ability to render a calendar widget on the page
* that can be manipulated to select a single date, move back and forth between
* months and years.
* <p>To construct the placeholder for the calendar widget, the code is as
* follows:
*	<xmp>
*		<div id="calContainer"></div>
*	</xmp>
* </p>
* <p>
* <strong>NOTE: As of 2.4.0, the constructor's ID argument is optional.</strong>
* The Calendar can be constructed by simply providing a container ID string, 
* or a reference to a container DIV HTMLElement (the element needs to exist 
* in the document).
* 
* E.g.:
*	<xmp>
*		var c = new YAHOO.widget.Calendar("calContainer", configOptions);
*	</xmp>
* or:
*   <xmp>
*       var containerDiv = YAHOO.util.Dom.get("calContainer");
*		var c = new YAHOO.widget.Calendar(containerDiv, configOptions);
*	</xmp>
* </p>
* <p>
* If not provided, the ID will be generated from the container DIV ID by adding an "_t" suffix.
* For example if an ID is not provided, and the container's ID is "calContainer", the Calendar's ID will be set to "calContainer_t".
* </p>
* 
* @namespace YAHOO.widget
* @class Calendar
* @constructor
* @param {String} id optional The id of the table element that will represent the Calendar widget. As of 2.4.0, this argument is optional.
* @param {String | HTMLElement} container The id of the container div element that will wrap the Calendar table, or a reference to a DIV element which exists in the document.
* @param {Object} config optional The configuration object containing the initial configuration values for the Calendar.
