Henry Weller 3e761d6a41 foamyHexMesh: Added cell sizing based on local surface closeness

First run the surfaceFeatureExtract with the "closeness" option enabled in the
surfaceFeatureExtractDict to extract the surface closeness point field

    // Out put the closeness of surface elements to other surface elements.
    closeness               yes;

Then enable cell sizing based on local surface closeness by specifying the
"internalCloseness" options in the foamyHexMeshDict e.g.

motionControl
{
    defaultCellSize             4;

    minimumCellSizeCoeff        0.1;
    maxSmoothingIterations      100;
    maxRefinementIterations     2;

    shapeControlFunctions
    {
        geometry
        {
            type                        searchableSurfaceControl;
            priority                    1;
            mode                        inside;

            surfaceCellSizeFunction     nonUniformField;

            cellSizeCalculationType     automatic;

            curvature                   false;
            curvatureFile               dummy;
            featureProximity            false;
            featureProximityFile        dummy;
            internalCloseness           true;
            internalClosenessFile       geometry.internalPointCloseness;
            internalClosenessCellSizeCoeff 25;
            curvatureCellSizeCoeff      0;
            maximumCellSizeCoeff        1;
            cellSizeFunction            uniform;
        }
    }
}
