// The typical MFC app, frame creation code + AboutDlg handling
//
// NS_InitEmbedding() is called in InitInstance()
//
// NS_TermEmbedding() is called in ExitInstance()
// ExitInstance() also takes care of cleaning up of
// multiple browser frame windows on app exit
//
// Code to handle the creation of a new browser window

the default implementation uses XUL, not native windows. Embedding

the same CID and Contract ID as the default's.
Note that this example implements the service in a separate DLL,

also have been done in the same module, without a separate DLL.
