// .NAME vtkSQRandomSeedPoints - create a random cloud of points
// .SECTION Description
// vtkSQRandomSeedPoints 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.
