/**
    @class wxHtmlHelpWindow

    This class is used by wxHtmlHelpController to display help within a frame or
    dialog, but you can use it yourself to create an embedded HTML help window.

    For example:
    @code
        // m_embeddedHelpWindow is a wxHtmlHelpWindow
        // m_embeddedHtmlHelp is a wxHtmlHelpController

        // Create embedded HTML Help window
        m_embeddedHelpWindow = new wxHtmlHelpWindow;
        m_embeddedHtmlHelp.UseConfig(config, rootPath); // Set your own config object here
        m_embeddedHtmlHelp.SetHelpWindow(m_embeddedHelpWindow);
        m_embeddedHelpWindow->Create(this, wxID_ANY, wxDefaultPosition, GetClientSize(),
                                     wxTAB_TRAVERSAL|wxBORDER_NONE, wxHF_DEFAULT_STYLE);
        m_embeddedHtmlHelp.AddBook(wxFileName(wxT("doc.zip")));
    @endcode

    You should pass the style wxHF_EMBEDDED to the style parameter of
    wxHtmlHelpController to allow the embedded window to be destroyed
    independently of the help controller.
