 DESCRIPTION:

  Virtual Methods ( or NULL Methods in Classy ) are used to substitute a 
  non-existing Method with a 'dummy' message. A virtual Method will do
  nothing when it is called, and return NIL to the caller. 

  The only benefit of a virtual Method is that the Application will not bomb
  with a "message not found" error when the message is received.
  This is very usefull if you have to provide a common class interface :
  Class A may need a SETFOCUS Method, while Class B does not; if you    
  provide a VIRTUAL method SetFocus in Class B, then you can send the
  SetFocus message to both Objects ..
