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 "Panel #" + index; // This would have each tab with the text 'Panel #X' where X = index
}
