     gUpdateDataMessage is a class to represent an update data message.
     gUpdateDataMessage is inherited from the virtual class,
     gUpdateMessage. Whenever a gUpdateDataMessage is created
     (initialized), the next step is to call the handleMessage method
     to act upon that message and update the data.
