Class
    Foam::edgeSlipDisplacementPointPatchVectorField

Description
    Displacement follows an edgeMesh. Use in a displacementMotionSolver
    as a bc on the pointDisplacement field.

    Needs:
    - file : name of edgeMesh. Either:
        - .extendedFeatureEdgeMesh (read from  constant/extendedFeatureEdgeMesh)
        - or .eMesh in or a known format (read from constant/triSurface)
    - frozenPointsZone : empty or name of pointZone containing points
                         that do not move
    - velocity : maximum displacement velocity
