add inertial damping

[tcordeboeuf]

Is that possible to add an inertial damping to reduce the inetia when the driving animation is really fast. That's a non physical thing but that help to stabilise a simulation.

You can find the paper that explain the inertial damping here https://viterbi-web.usc.edu/~jbarbic/adjustableDynamics/
