The following line shows how to create a zAppFrame class. 
zAppFrame *win = new zAppFrame(0, new zSizer, zSTDFRAME, "GOLDENBERG");

  The arguments to the constructor are:

     - The parent of the frame.
     - A zAsizer used to position the frame.
     - The style attributes for the frame.
     - The title of the frame to be displayed 
      in the caption bar, if present.

        When  the zAppFrame class creates the application,
you define a new type of frame, adding code to create the 
various panes and controls that will inhabit the frame,
handle the menu, and control the option of the application.
