// .NAME vtkCellDistanceSelector - select neighbor cells up to a distance
//
// .SECTION Description
// This filter grows an input selection by iteratively selecting neighbor
// cells (a neighbor cell is a cell that shares a vertex/edge/face), up to
// a given topological distance to the selected neighborhood (number of times
// we add neighbor cells).
// This filter takes a vtkSelection and a vtkCompositeDataSet as inputs.
// It outputs a vtkSelection identifying all the selected cells.
//
