SoButtonEvent — base class for all button events

SoButtonEvent  represents  generic button press and release events in the Inventor event model. It is the
       base  class  for  device-specific  button  events,  namely   SoKeyboardEvent,   SoMouseButtonEvent,   and
       SoSpaceballButtonEvent. This class stores the down/up state of the button when the event occurred.
