+	/**
+	 * Provides drag and drop functionality<br>
+	 * a DragDrop instance is created for each usage pattern and then used over and over again<br>
+	 * first a dragObj is defined - this is the jquery node that will be dragged around<br>
+	 * second, the event callbacks are defined - these allow you control the ui during dragging and run functions when successfully dropping<br>
+	 * thirdly drop targets are defined - this is a list of DOM nodes, the constructor works in one of two modes:
+	 * <li>without targets - objects can be picked up and dragged around, dragStart and dragStop events fire</li>
+	 * <li>with targets - as objects are dragged over targets dragOver, dragOut and DragDrop events fire
+	 * to start dragging call the DragDrop.pickup_handler() function, dragging stops when the mouse is released.
+	 * @constructor
+	 * The following options are supported
+	 * <dt>targetSelector</dt>
+	 *   <dd>an argument passed directly to jquery to create a list of targets, as such it can be a CSS style selector, or an array of DOM nodes<br>if target selector is null the DragDrop does Drag only and will not fire dragOver dragOut and dragDrop events</dd>
+	 * <dt>pickupSelector</dt>
+	 *   <dd>a jquery selector. The pickup_handler is automatically bound to matched elements (eg clicking on these elements starts the drag). if pickupSelector is null, the pickup_handler must be manually bound <code>$(el).bind("mousedown", dragdrop.pickup_handler)</code></dd>
+	 * <dt>dragObj</dt>
+	 *   <dd>the jQuery element to drag around when pickup is called. If not defined, dragObj must be set in onDragStart</dd>
+	 * <dt>draggingClass</dt>
+	 *   <dd>the class(es) added to items when they are being dragged</dd>
+	 * The following observables are supported
+	 * <dt>dragStart</dt>
+	 *   <dd>a callback when start to drag<br><code>function(jEv)</code></dd>
+	 * <dt>dragOver</dt>
+	 *   <dd>a callback when we drag into a target<br><code>function(jEl)</code></dd>
+	 * <dt>dragOut</dt>
+	 *   <dd>a callback when we drag out of a target, or when we drop over a target<br><code>function(jEl)</code></dd>
+	 * <dt>dragDrop</dt>
+	 *   <dd>a callback when we drop on a target<br><code>function(jEl)</code></dd>
+	 * <dt>dragStop</dt>
+	 *   <dd>a callback when we stop dragging<br><code>function(jEv)</code></dd>
