+		//		`args.properties`
+		//
+		// description:
+		//		`dojo.animateProperty` is the foundation of most `dojo.fx`
+		//		animations. It takes an object of "properties" corresponding to
+		//		style properties, and animates them in parallel over a set
+		//		duration.
+		//
+		// example:
+		//		A simple animation that changes the width of the specified node.
+		//	|	dojo.animateProperty({
+		//	|		node: "nodeId",
+		//	|		properties: { width: 400 },
+		//	|	}).play();
+		//		Dojo figures out the start value for the width and converts the
+		//		integer specified for the width to the more expressive but
+		//		verbose form `{ width: { end: '400', units: 'px' } }` which you
+		//		can also specify directly. Defaults to 'px' if ommitted.
+		//
+		// example:
+		//		Animate width, height, and padding over 2 seconds... the
+		//		pedantic way:
+		//	|	dojo.animateProperty({ node: node, duration:2000,
+		//	|		properties: {
+		//	|			width: { start: '200', end: '400', units:"px" },
+		//	|			height: { start:'200', end: '400', units:"px" },
+		//	|			paddingTop: { start:'5', end:'50', units:"px" }
+		//	|		}
+		//	|	}).play();
+		//		Note 'paddingTop' is used over 'padding-top'. Multi-name CSS properties
+		//		are written using "mixed case", as the hyphen is illegal as an object key.
+		//
+		// example:
+		//		Plug in a different easing function and register a callback for
+		//		when the animation ends. Easing functions accept values between
+		//		zero and one and return a value on that basis. In this case, an
+		//		exponential-in curve.
+		//	|	dojo.animateProperty({
+		//	|		node: "nodeId",
+		//	|		// dojo figures out the start value
+		//	|		properties: { width: { end: 400 } },
+		//	|		easing: function(n){
+		//	|			return (n==0) ? 0 : Math.pow(2, 10 * (n - 1));
+		//	|		},
+		//	|		onEnd: function(node){
+		//	|			// called when the animation finishes. The animation
+		//	|			// target is passed to this function
+		//	|		}
+		//	|	}).play(500); // delay playing half a second
+		//
+		// example:
+		//		Like all `dojo.Animation`s, animateProperty returns a handle to the
+		//		Animation instance, which fires the events common to Dojo FX. Use `dojo.connect`
+		//		to access these events outside of the Animation definiton:
+		//	|	var anim = dojo.animateProperty({
+		//	|		node:"someId",
+		//	|		properties:{
+		//	|			width:400, height:500
+		//	|		}
+		//	|	});
+		//	|	dojo.connect(anim,"onEnd", function(){
+		//	|		console.log("animation ended");
+		//	|	});
+		//	|	// play the animation now:
+		//	|	anim.play();
+		//
+		// example:
+		//		Each property can be a function whose return value is substituted along.
+		//		Additionally, each measurement (eg: start, end) can be a function. The node
+		//		reference is passed direcly to callbacks.
+		//	|	dojo.animateProperty({
+		//	|		node:"mine",
+		//	|		properties:{
+		//	|			height:function(node){
+		//	|				// shrink this node by 50%
+		//	|				return dojo.position(node).h / 2
+		//	|			},
+		//	|			width:{
+		//	|				start:function(node){ return 100; },
+		//	|				end:function(node){ return 200; }
+		//	|			}
+		//	|		}
