How to use Mouse and Touch Events in Starling

There is often confustion by new adaptors of Starling about what Events to use to handle touch/clicks.

Unlike AIR’s native TOUCH_BEGIN, TOUCH_END events, Starling uses a single TOUCH event, the type of touch is then extracted in the event handler through the event (e) object.
See below.

private function onTouch(e:TouchEvent):void
		{
			var touch:Touch = e.getTouch(stage);
			if(touch)
			{
				if(touch.phase == TouchPhase.BEGAN)
				{
                              //There was a touch (MouseDown)
				}

				else if(touch.phase == TouchPhase.ENDED)
				{
                                //The Touch ended (MouseUp)
				}

				else if(touch.phase == TouchPhase.MOVED)
				{
                                //dragging
				}
			}

		}

There reason its setup this way is to be able to easily handle multiple touch events simultaneously.
I will discuss the tracking of multi-touches in another post.
