// .NAME vtkGaussianRandomSequence - Gaussian sequence of pseudo random numbers
// .SECTION Description
// vtkGaussianRandomSequence is a sequence of pseudo random numbers
// distributed according to the Gaussian/normal distribution (mean=0 and
// standard deviation=1)
//
// This is just an interface.
