I find that frequently I have the cumbersome

   double ptot = Math.sqrt(t.getMomentumX()*t.getMomentumX() +
                                    t.getMomentumY()*t.getMomentumY() +
                                    t.getMomentumZ()*t.getMomentumZ());

at several places throughout my code (I see in many other peoples
also).  Since ptot is used so  frequently doesn't make sense to have
it as a method in the particle and track classes? (Sorry if this is an
old and discarded issue). I don't have a strong opinion on the method
name.
