// a supporting C++ bridge object to register for notifications from the
// TabStripModel. The Obj-C part of this class handles drag and drop and all
// the other Cocoa-y aspects.

// When a new tab is created, it loads the contents, including
// toolbar, from a separate nib file and replaces the contentView of the
// window. As tabs are switched, the single child of the contentView is
// swapped around to hold the contents (toolbar and all) representing that tab.
