// The \subdoxygen{Statistics}{NormalVariateGenerator} generates random
// variables according to the standard normal distribution (mean = 0,
// standard deviation = 1).
//
// To use the class in a project, we must link the \code{itkStatistics}
// library to the project.
//
// To begin the example we include the header file for the class.

  // The NormalVariateGenerator is a non-templated class. We simply call
  // the \code{New()} method to create an instance. Then, we provide the seed
  // value using the \code{Initialize(seed value)}.
