   When creating this widget, you can create it as either single-way
   or multi-way by passing the multiway arguement as either FALSE or TRUE. 

   If creating a single-way guru, the widget is designed to only pass
   thru a linear sequence of pages. The page switching and button
   sensitivities are handled internally and you only need to connect
   to the "cancel" and "apply" signals. Connecting to the other
   signals is not recommended.

   If creating a multi-way guru, the widget can pass thru any sequence
   of pages. Use this when the need for one or more pages depends on
   user input at a previous page. You will have to capture all the
   button clicks and manually handle all the page switching and button
   sensitivities, using the _set_page(), _next_page(), _prev_page()
   and _set_state() methods.

   If the dialog arguement is not NULL, the widget will assume it is
   an empty dialog and wrap itself inside it.
   
   If the graphic arguement is not NULL, the guru will include a graphic.
