    @class WebView
    WebView manages the interaction between WebFrameViews and WebDataSources.  Modification
    of the policies and behavior of the WebKit is largely managed by WebViews and their
    delegates.
    
    <p>
    Typical usage:
    </p>
    <pre>
    WebView *webView;
    WebFrame *mainFrame;
    
    webView  = [[WebView alloc] initWithFrame: NSMakeRect (0,0,640,480)];
    mainFrame = [webView mainFrame];
    [mainFrame loadRequest:request];
    </pre>
    
    WebViews have the following delegates:  WebUIDelegate, WebResourceLoadDelegate,
    WebFrameLoadDelegate, and WebPolicyDelegate.
    
    WebKit depends on the WebView's WebUIDelegate for all window
    related management, including opening new windows and controlling the user interface
    elements in those windows.
    
    WebResourceLoadDelegate is used to monitor the progress of resources as they are
    loaded.  This delegate may be used to present users with a progress monitor.
    
    The WebFrameLoadDelegate receives messages when the URL in a WebFrame is
    changed.
    
    WebView's WebPolicyDelegate can make determinations about how
    content should be handled, based on the resource's URL and MIME type.
