+/**
+	A control that shows the current progress of a process in a horizontal bar.
+	
+		{kind: "onyx.ProgressBar", progress: 10}
+	
+	To animate progress changes, call the *animateProgressTo* method:
+	
+		this.$.progressBar.animateProgressTo(50);
+		
+	You may customize the color of the bar by applying a style via the
+	*barClasses* property, e.g.:
+	
+		{kind: "onyx.ProgressBar", barClasses: "onyx-dark"}
+	
+	When the *showStripes* property is true (the default), stripes are shown in
+	the progress bar; when *animateStripes* is true (also the default), these
+	stripes are animated. The animated stripes use CSS3 gradients and animation
+	to produce the effects.  In browsers that don't support these features, the
+	effects will not be visible.
