Patch contributed by Juho Peltola, VTT

The new JohnsonJacksonSchaefferFrictionalStress model is included and
the LBend tutorial case to demonstrate the need for the changes to the
frictional stress models.

ccbb0b93c6 rigidBodyDynamics: Added support for running in parallel 
The joint-space dynamics is solved on the master processor only and the
resulting joint-state distributed to the slave processors on which the
body-state is then updated.  This guarantees consistency of the body
position and orientation on all processors.

04e4e1a7bb 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.

6a5d5e903e septernion: Changed definition of the forward transformation for consistency with spatialTransform 
inline Foam::vector Foam::septernion::transformPoint(const vector& v) const
{
    return r().transform(v - t());
}

Now there is a 1:1 correspondence between septernion and
spatialTransform and a septernion constructor from spatialTransform
provided.

Additionally "septernion::transform" has been renamed
"septernion::transformPoint" to clarify that it transforms coordinate
points rather than displacements or other relative vectors.

df1cb90dc6 rigidBodyDynamics: Simplify handling of quaternions by maintaining a unit quaternion in the joint state field 'q' 
'w' is now obtained from 'v' using the relation w = sqrt(1 - |sqr(v)|)
and 'v' is stored in the joint state field 'q' and integrated in the
usual manner but corrected using quaternion transformations.

c07bc87f95 rigidBodyDynamics/rigidBodySolvers: Added run-time selectable solvers to integrate the rigid-body motion 
Currently supported solvers: symplectic, Newmark, CrankNicolson

The symplectic solver should only be used if iteration over the forces
and body-motion is not required.  Newmark and CrankNicolson both require
iteration to provide 2nd-order behavior.

See applications/test/rigidBodyDynamics/spring for an example of the
application of the Newmark solver.
