/**
	@class ProgressBar
	The progress bar widget shows a control that indicates the progress percentage of an on-going operation. This widget can be scaled to fit inside a parent container.

	To add a progress bar widget to the application, use the following code:

		<div id="foo" data-role="progressbar"</div>
*/
/**
	@event change
	The progress bar can define a callback for the change event, which is fired when the progress value is changed:
		<div id="foo" data-role="progressbar"></div>
		$("#foo").bind("change", function (ev, val) {
			Console.log("Value is changed to " + val);
		});
*/
/**
	@method value
	You can use the value method with the pickers to set or get the current default progress bar value:

		<div id="foo" data-role="progressbar"></div>
		var oldVal = $("#foo").progressbar("value");
		$("#foo").progressbar("value", 50);
