// NOTES:
//
// A CWebBrowserSB object is ALWAYS paired with CWebBrowserOC, and bahaves
// as a "ShellExplorer" OC together. CWebBrowserOC exports OLE control
// interfaces and an OLE automation interface (IWebBrowser) to the
// container. CWebBrowserSB exports IShellBrowser interface and a few other
// interfaces to the containee (IShellView object and DocObject).
//
// It's important to know that those objects have pointers (not interface
// pointers but explicit object pointers) to each other. In order to avoid
// a circular reference, we don't AddRef to the pointer to CWebBrowserOC
// (_psvo).
