Description
    Sample field data with a choice of interpolation schemes, sampling options
    and write formats.

    Keywords:

    @param setFormat : set output format, choice of \n
      - xmgr
      - jplot
      - gnuplot
      - raw

    @param surfaceFormat : surface output format, choice of \n
      - null        : suppress output
      - foamFile    : separate points, faces and values file
      - dx          : DX scalar or vector format
      - vtk         : VTK ascii format
      - raw         : x y z value format for use with e.g. gnuplot 'splot'.
      - obj         : Wavefron stl. Does not contain values!
      - stl         : ascii stl. Does not contain values!

    @param interpolationScheme : interpolation scheme, choice of \n
      - cell          : use cell-centre value; constant over cells (default)
      - cellPoint     : use cell-centre and vertex values
      - cellPointFace : use cell-centre, vertex and face values. \n
        -# vertex values determined from neighbouring cell-centre values
        -# face values determined using the current face interpolation scheme
           for the field (linear, limitedLinear, etc.)

    @param fields : list of fields to sample

    @param sets : list of sets to sample, choice of \n
      - uniform             evenly distributed points on line
      - face                one point per face intersection
      - midPoint            one point per cell, inbetween two face intersections
      - midPointAndFace     combination of face and midPoint

      - curve               specified points, not nessecary on line, uses
                            tracking
      - cloud               specified points, uses findCell

        Option axis: how to write point coordinate. Choice of
          - x/y/z: x/y/z coordinate only
          - xyz: three columns
            (probably does not make sense for anything but raw)
          - distance: distance from start of sampling line (if uses line)
            or distance from first specified sampling point

        Type specific options:
            uniform, face, midPoint, midPointAndFace : start and end coordinate
            uniform: extra number of sampling points
            curve, cloud: list of coordinates

    @param surfaces : list of surfaces to sample, choice of \n
      - plane : values on plane defined by point, normal.
      - patch : values on patch.
