/**

* @brief Checks if target responds to 'move<Key>:toIndex:'. If so, then uses that method to move. Otherwise, calls super.

* This class overrides NSMoveCommand, and is more useful for those cases when a move is not a remove/insert pair.

* The target can specify exactly how to get the object into itself, in its own move<Key>:toIndex: method.
