rigidBodyMeshMotion: displacementMotionSolver for the mesh-motion of multiple articulated rigid-bodies

The motion of the bodies is integrated using the rigidBodyDynamics
library with joints, restraints and external forces.

The mesh-motion is interpolated using septernion averaging.

This development is sponsored by Carnegie Wave Energy Ltd.
