Make DOM elements draggable and re-layout.

##Usage

The DOM structure is simple, put all elements you want it be draggable in a container. Here is an example:

<div id="dragBox">
	<div>1</div>
	<div>2</div>
	<div>3</div>
	<div>4</div>
	<div>5</div>
	<div>6</div>
</div>

Simply use Draggable function like so:

Draggable(document.getElementById('dragBox'));

##Config Options The second parameter of the Draggable function is an object of config options:

• positioned Boolean ( default: true ) - set the draggable elements positioned
• onDrag Function - runs when start drag
• onDrop Function - runs when end drag

##Example

var box = document.getElementById('dragBox');

Draggable(box, {
	positioned: true,
	onDrag: function(index, elem){},
	onDrop: function(index, elem){}
});
