// .NAME vtkPointSource - create a random cloud of points
// .SECTION Description
// vtkPointSource is a source object that creates a user-specified number
// of points within a specified radius about a specified center point.
// By default location of the points is random within the sphere. It is
// also possible to generate random points only on the surface of the
// sphere. The output PolyData has the specified number of points and
// 1 cell - a vtkPolyVertex containing all of the points.
