00027     This class handles user interaction with the easyGUI pages that deal with the nudge and damp factors 
00028     for the various components. These pages are all so similar that it seems wasteful 
00029     to have a separate class for each. 
00030     
00031     This class also deals with the Fan Power page, since that is very similar to the Nudge and Damp pages 
00032     (and the Fan Power parameters are handled in the "Heating Control" frame in the 500 Series GC VB6 application, 
00033     just like the Nudge and Damp pages).
00034     
00035     Note that this class is a singleton - we do not need or want there to be more than one instance of it
00036     (we do not want multiple values for the various nudge and damp factors, etc, nor will we show 
00037     more than one easyGUI page to the user at the same time).
