MOTabView extends NSTabView to add drag & drop support.
Superclass: NSTabView
MOTabView extends NSTabView to add drag & drop support. The tab view's delegate can implement various new methods to support dragging of tabs and accepting drops. As a drag source, MOTabView allows tabs to be dragged. As a drag destination MOTabView supports drops either "onto" a tab or "between" tabs. In both cases, it is left to the delegate to deal with the actual pasteboard content.
