  // .NAME vtkvmtkSurfaceProjectCellArray - ...
  // .SECTION Description
  // Projects a cell array from a reference surface
  // For each cell, the cell value chosen is the one of the cell on the reference surface which has the
  // smallest minimum distance to the cell vertices.
  // If the distance of any vertices in the cell to the reference surface is higher than
  // DistanceTolerance, the cell array values are set to DefaultValue for each component.
