+**  CAUSE A NOVA TO OCCUR
+**
+**	A nova occurs.  It is the result of having a star hit with
+**	a photon torpedo.  There are several things which may happen.
+**	The star may not be affected.  It may go nova.  It may turn
+**	into a black hole.  Any (yummy) it may go supernova.
+**
+**	Stars that go nova cause stars which surround them to undergo
+**	the same probabilistic process.  Klingons next to them are
+**	destroyed.  And if the starship is next to it, it gets zapped.
+**	If the zap is too much, it gets destroyed.
