Class
    Foam::sampledMeshedSurfaceNormal

Description
    Variant of sampledMeshedSurface that samples the surface-normal component
    of a vector field.

    Returns a vector field with the value in the first component and sets
    the other two to zero.

    This is often embedded as part of a sampled surfaces function object.

Usage
    Example of function object partial specification:
    \verbatim
    surfaces
    {
        surface1
        {
            type    sampledMeshedSurfaceNormal;
            surface something.obj;
            source  cells;
        }
    }
    \endverbatim

    Where the sub-entries comprise:
    \table
        Property | Description                             | Required | Default
        type     | meshedSurfaceNormal                     | yes      |
        surface  | surface name in triSurface/             | yes      |
        patches  | Limit to named surface regions (wordRes) | no  |
        source   | cells/insideCells/boundaryFaces         | yes      |
        keepIds  | pass through id numbering               | no       | false
    \endtable
