 // THO ADDED FUNCTIONALITY:
 Config:
 updateHeader: true,                 // If the element span.title should update with content from each slide LI (li div.title)
 updateText: true,                 // If the element ID > .textContent should update with content from each slide LI (li div.textContent)
 updateMenu: true,                 // If the element ID > .textContent's ul should update to reflect the current slide's heirarchy

 New methods to customize/simplify usage.  DO NOT just upgrade to a newer version of AnySlider

 To use the navigationFormatter function, you must have a function that
 accepts two paramaters, and returns a string of HTML text.

 index = integer index (1 based);
 panel = jQuery wrapped LI item this tab references
 @return = Must return a string of HTML/Text

 navigationFormatter: function(index, panel){
 return index + " Panel"; // This would have each tab with the text 'X Panel' where X = index
 }

 createSlideshow(id, path)

 This method is used to create a slideshow-rotator, originally designed to be used to
 display slides when a conference is over.  It takes two parameters:

 1) id: an HTML ID attribute to be used to identify the DOM element.  (should be unique,
 since it is an ID)

 2) path: the path to a HTML-formatted (so JSP, HTML, whatever) file that contains a
 formatted UL of content.  The basic layout for this content should be as follows:

 <ul class="slideshowRotatorContentList"><!-- It is important to have this class applied to the UL -->
 <li>
 <div class="title"><!-- THE TITLE GOES HERE --></div>
 <div class="image"><img src="<!-- THE SLIDE IMAGE GOES HERE, it MUST be the appropriate dimensions -->" width="522" height="355"></div>
