rigidBodyMeshMotion: Added support for dynamic mesh refinement/unrefinement

Browse Source 
The floatingObject tutorial has been update to demonstrate this functionality by
adding the following topoChanger entry to dynamicMeshDict:

topoChanger
{
    type    refiner;

    libs    ("libfvMeshTopoChangers.so");

    // How often to refine
    refineInterval  1;

    // Field to be refinement on
    field           alpha.water;

    // Refine field in between lower..upper
    lowerRefineLevel 0.001;
    upperRefineLevel 0.999;

    // Have slower than 2:1 refinement
    nBufferLayers   1;

    // Refine cells only up to maxRefinement levels
    maxRefinement   1;

    // Stop refinement if maxCells reached
    maxCells        200000;

    // Flux field and corresponding velocity field. Fluxes on changed
    // faces get recalculated by interpolating the velocity. Use 'none'
    // on surfaceScalarFields that do not need to be reinterpolated.
    correctFluxes
    (
        (phi none)
        (nHatf none)
        (rhoPhi none)
        (alphaPhi.water none)
        (meshPhi none)
        (ghf none)
    );

    // Write the refinement level as a volScalarField
    dumpLevel       true;
}

Note that currently only single rigid body motion is supported (but multi-body
support will be added shortly) and the Crank-Nicolson scheme is not supported.
