+/**\r
+ * With the Draggables plugin, Droppable allows you to create drop zones for draggable elements.\r
+ *\r
+ * @name Droppable\r
+ * @cat Plugins/Interface\r
+ * @param Hash options A hash of options\r
+ * @option String accept The class name for draggables to get accepted by the droppable (mandatory)\r
+ * @option String activeclass When an acceptable draggable is moved, the droppable gets this class\r
+ * @option String hoverclass When an acceptable draggable is inside the droppable, the droppable gets\r
+ * this class\r
+ * @option String tolerance Choose from 'pointer', 'intersect', or 'fit'. The pointer options means\r
+ * that the pointer must be inside the droppable in order for the draggable\r
+ * to be dropped. The intersect option means that the draggable must intersect\r
+ * the droppable. The fit option means that the entire draggable must be\r
+ * inside the droppable.\r
+ * @option Function onDrop When an acceptable draggable is dropped on a droppable, this callback is\r
+ * called. It passes the draggable DOMElement as a parameter.\r
+ * @option Function onHover When an acceptable draggable is hovered over a droppable, this callback\r
+ * is called. It passes the draggable DOMElement as a parameter.\r
+ * @option Function onOut When an acceptable draggable leaves a droppable, this callback is called.\r
+ * It passes the draggable DOMElement as a parameter.\r
+ * @example $('#dropzone1').Droppable(\r
+ * {\r
+ * accept : 'dropaccept', \r
+ * activeclass: 'dropzoneactive', \r
+ * hoverclass: 'dropzonehover',\r
+ * ondrop: function (drag) {\r
+ * alert(this); //the droppable\r
+ * alert(drag); //the draggable\r
