There is no need for a damping dispatcher IMHO.
Damping is a part of the numerical integration scheme, and as such it 
would be consistent to damp equations at the same time you integrate 
laws of motion.
What I plan is to simply merge MomentumDamping, ForceDamping, 
LeapfrogMomentum and LeapFrogPosition.
It will make only one loop for integrating damped equations of motion 
(i.e. what 99% of simulations need), rather than 4.
