Progress Indicator Helper

Use the optional options param to pass custom show or hide functions. Provides functions show/hide.

function ProgressIndicator(element, options) {
        var element = $(element);
        var my_options = {show:Element.show, hide:Element.hide};
        Object.extend(my_options, options || {});
        this.show = function() { my_options.show(element) }
        this.hide = function() { my_options.hide(element) }
        this.hide();
}

Example

var p = new ProgressIndicator($("my_element"));
p.show();

var q = new ProgressIndicator("my_other_element",
                             {show: Effect.Appear, 
                              hide:Effect.Fade});
q.show();
$("my_other_element").onclick = q.hide;


Requires prototype for a few things.
