// .NAME vtkBoxMuellerRandomSequence - Gaussian sequence of pseudo random numbers implemented with the Box-Mueller transform
// .SECTION Description
// vtkGaussianRandomSequence is a sequence of pseudo random numbers
// distributed according to the Gaussian/normal distribution (mean=0 and
// standard deviation=1).
//
// It based is calculation from a uniformly distributed pseudo random sequence.
// The initial sequence is a vtkMinimalStandardRandomSequence.
