anythingSlider v1.2
By Chris Coyier: http://css-tricks.com
with major improvements by Doug Neiner: http://pixelgraphics.us/
based on work by Remy Sharp: http://jqueryfordesigners.com/
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
}
