Class
    Foam::displacementLayeredMotionMotionSolver

Description
    Mesh motion solver for an (multi-block) extruded fvMesh. Gets given the
    structure of the mesh blocks and boundary conditions on these blocks.

    The displacementLayeredMotionCoeffs subdict of dynamicMeshDict specifies
    per region (=cellZone) the boundary conditions on two opposing patches
    (=faceZones). It then interpolates the boundary values using topological
    walking so requires the cellZone to be a layered mesh.

    The boundary conditions on faceZones are currently:

    follow: the faceZone follows the overall mesh displacement.
            Use this for faceZones on boundary faces (so it uses the
            proper boundary conditions on the pointDisplacement).

    uniformFollow: like 'follow' but takes the average value of
            a specified 'patch' (which is not necessarily colocated)

    fixedValue: fixed value.

    timeVaryingUniformFixedValue: table-driven fixed value.

    slip: the second of a pair of faceZones follows the tangential movement
          specified by the first faceZone. (= removes the normal component).
