// Replaces DamageHelperGeneric.uc.  The HandleDamage() call is invoked directly
// from the U2Pawn eventTakeDamage().  Whereas the DamageHelperGeneric was 
// pawn-centric (i.e., oriented toward creature-specific damage effects), the 
// U2DamageType is damage-centric (i.e., oriented toward damage type effects).
//
// Specific damage effects may be specified within U2DamageType sub-classes.
