Class
    Foam::searchableSurfaceToCell

Description
    A \c topoSetCellSource to select cells whose cell
    centre enclosed by a given \c searchableSurface.

    Operands:
    \table
      Operand   | Type        | Location
      input     | triSurface  | $FOAM_CASE/constant/triSurface/<file>
      output    | cellSet     | $FOAM_CASE/constant/polyMesh/sets/<set>
    \endtable

Usage
    Minimal example by using \c system/topoSetDict.actions:
    \verbatim
    {
        // Mandatory (inherited) entries
        name        <name>;
        type        cellSet;
        action      <action>;

        // Mandatory entries
        source      searchableSurfaceToCell;
        surfaceType <surfaceTypeName>;

        // Optional entries
        surfaceName <surfaceName>;
    }
    \endverbatim

    where the entries mean:
    \table
      Property   | Description                         | Type | Req'd | Dflt
      name       | Name of cellSet                     | word |  yes  | -
      type       | Type name: cellSet                  | word |  yes  | -
      action     | Action applied on cells - see below | word |  yes  | -
      source     | Source name: searchableSurfaceToCell | word |  yes | -
      surfaceType | The searchable surface type        | word |  yes  | -
      surfaceName | Name for the IOobject              | word | no | mesh-name
    \endtable

    Options for the \c action entry:
    \verbatim
      new      | Create a new cellSet from selected cells
      add      | Add selected cells into this cellSet
      subtract | Remove selected cells from this cellSet
    \endverbatim
