eventDragStop ============= Triggered when event dragging stops.
function( *event*, *jsEvent*, *ui*, *view* ) { }
This callback is *guaranteed* to be triggered after the user drags an event, even if the event doesn't change date/time. It is triggered before the event's information has been modified (if moved to a new date/time) and before the [eventDrop]() callback is triggered. `event` is an [Event Object](../event_data/Event_Object) that hold the event's information (date, title, etc). `jsEvent` holds the native JavaScript event with low-level information such as mouse coordinates. `ui` holds the [jQuery UI object](http://jqueryui.com/demos/draggable/). `view` holds the current [View Object](../views/View_Object).
