+/**
+ * Creates a higher-order component (HOC) supporting drag & drop and optionally resizing
+ * of events:
+ *
+ * ```js
+ * import Calendar from 'react-big-calendar'
+ * import withDragAndDrop from 'react-big-calendar/lib/addons/dragAndDrop'
+ * export default withDragAndDrop(Calendar)
+ * ```
+ *
+ * Set `resizable` to true in your calendar if you want events to be resizable.
+ *
+ * The HOC adds `onEventDrop`, `onEventResize`, and `onDragStart` callback properties if the events are
+ * moved or resized. These callbacks are called with these signatures:
+ *
+ * ```js
+ * function onEventDrop({ event, start, end, allDay }) {...}
+ * function onEventResize(type, { event, start, end, allDay }) {...} // type is always 'drop'
+ * function onDragStart({ event, action, direction }) {...}
+ * ```
+ *
+ * Moving and resizing of events has some subtlety which one should be aware of.
+ *
+ * In some situations, non-allDay events are displayed in "row" format where they
+ * are rendered horizontally. This is the case for ALL events in a month view. It
+ * is also occurs with multi-day events in a day or week view (unless `showMultiDayTimes`
+ * is set).
+ *
+ * When dropping or resizing non-allDay events into a the header area or when
+ * resizing them horizontally because they are displayed in row format, their
+ * times are preserved, only their date is changed.
+ *
+ * If you care about these corner cases, you can examine the `allDay` param suppled
+ * in the callback to determine how the user dropped or resized the event.
+ *
+ * Additionally, this HOC adds the callback props `onDropFromOutside` and `onDragOver`.
+ * By default, the calendar will not respond to outside draggable items being dropped
+ * onto it. However, if `onDropFromOutside` callback is passed, then when draggable
+ * DOM elements are dropped on the calendar, the callback will fire, receiving an
+ * object with start and end times, and an allDay boolean.
+ *
+ * If `onDropFromOutside` is passed, but `onDragOver` is not, any draggable event will be
+ * droppable onto the calendar by default. On the other hand, if an `onDragOver` callback
+ * *is* passed, then it can discriminate as to whether a draggable item is droppable on the
+ * calendar. To designate a draggable item as droppable, call `event.preventDefault`
+ * inside `onDragOver`. If `event.preventDefault` is not called in the `onDragOver`
+ * callback, then the draggable item will not be droppable on the calendar.
+ *
+ * * ```js
+ * function onDropFromOutside({ start, end, allDay }) {...}
+ * function onDragOver(DragEvent: event) {...}
+ * ```
