Class
    Foam::labelToPoint
 
Description
    A \c topoSetPointSource to select points
    based on explicitly given point labels.
 
    Operands:
    \table
      Operand   | Type     | Location
      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      labelToPoint;
        value
        (
            <pointLabel1>
            <pointLabel2>
            ...
        );
    }
    \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: labelToPoint            | word |  yes  | -
      value      | Input point labels                   | labelList | yes | -
    \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
