      Description

      The 2 sample Ad test does not work and produces wrong results
      See comparison with R using attached macro (using ROOT-R from
      http://root.cern.ch/drupal/content/how-use-r-root-root-r-interface
      The result is the p values obtained using 500 different pair of data samples obtained from the same normal distribution

      Also the time increases exponentially for large sample sizes
