/*C+ Notifier
*
*    DESCRIPTION:
*
*    A Notifier object is used to turn control of the 
*    application over to the windowing system.  When you do this,
*    the application is basically suspended until the user 
*    completes some interaction with the graphical objects 
*    (i.e., selects a Button, enters information into an 
*    AlphaNumericalInput field, attempts to QUIT the application 
*    by chosing the QUIT option from the BaseWindow's menu). 
*    When you turn control over to the windowing system, your 
*    application is then notified  of any events if you have 
*    written any Notify handlers, Event handlers, Done handlers 
*    or Repaint handlers.
*
*    INHERITED CLASSES:
*
*    UIObject - In addition to the normal benefits provided by the 
*    inheritance mechanism, inheriting the UIObject allows this
*    class to be used as UIObject class inside the Handlers.
*
*    PUBLIC MEMBER FUNCTIONS:
*
*    void       start ()            - Starts running the Notifier.
*    The Notifier object displays the first BaseWindow instantiated.
*
*    void       dispatchEvent ()    - Dispatches the next XView event and 
*    returns control to the caller
*
*    void       stop ()		    - Stop the XView notifier.
