 The energy package implements E-statistics (energy) tests and
 statistics for comparing distributions: multivariate normality,
 multivariate distance components and k-sample test for equal
 distributions, hierarchical clustering by e-distances, multivariate
 independence tests, distance correlation, goodness-of-fit
 tests. Energy-statistics concept based on a generalization of
 Newton's potential energy is due to Gabor J. Szekely.
