+/**
+	A control that looks like a switch with labels for two states. Each time a ToggleButton is tapped,
+	it switches its value and fires an onChange event.

+		buttonToggle: function(inSender, inEvent) {

+	To find out the value of the button, use getValue:
+	
+		queryToggleValue: function() {
+			return this.$.toggleButton.getValue();
+		}

+	The color of the toggle button can be customized by applying a background color:

+		{kind: "onyx.ToggleButton", style: "background-color: #35A8EE;"}
