Discussion
This method parallels the removeRows(at:withAnimation:) method of NSTableView and is used in a way similar to the removeObjects(at:) method of NSMutableArray. The method does nothing if parent is not expanded. If any of the child items is expanded, then all of its child rows are also be removed.
You can call this method multiple times within the same beginUpdates()/endUpdates() block; changes work just like modifying an array. Removing an item at an index beyond what is available throws an exception.
