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