// File Overview....
//
// When the CBrowserFrm creates this View:
//   - CreateBrowser() is called in OnCreate() to create the
//	   mozilla embeddable browser
//
// OnSize() method handles the window resizes and calls the approriate
// interface method to resize the embedded browser properly
//
// Command handlers to handle browser navigation - OnNavBack(), 
// OnNavForward() etc
//
// DestroyBrowser() called for cleaning up during object destruction
//
// Some important coding notes....
//
// 1. Make sure we do not have the CS_HREDRAW|CS_VREDRAW in the call
//	  to AfxRegisterWndClass() inside of PreCreateWindow() below
//	  If these flags are present then you'll see screen flicker when 
//	  you resize the frame window
//
// Next suggested file to look at : BrowserImpl.cpp
