Class
    Foam::searchableSurfaceToPoint

Description
    A \c topoSetPointSource to select points which are
    centre enclosed by a given \c searchableSurface.

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

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

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

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

    where the entries mean:
    \table
      Property   | Description                           | Type | Req'd | Dflt
      name       | Name of pointSet                      | word |  yes  | -
      type       | Type name: pointSet                   | word |  yes  | -
      action     | Action applied on points - see below  | word |  yes  | -
      source     | Source name: searchableSurfaceToPoint | 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 pointSet from selected points
      add      | Add selected points into this pointSet
      subtract | Remove selected points from this pointSet
    \endverbatim
