r3315

  • Documented some of the test functions with literature references.
  • Renamed Griewangk function as it is actually called Griewank function.
  • Schwefel is hard to find, used self-citation as Potter and DeJong's description from 1994 seems wrong
  • Levy is almost impossible to find and defined only for 2 variables, the implementation looks fishy (there was also a bug)
  • Booth, and Matyas are also just from a single website
  • Still missing is Zakharov and SumSquares
  • TODO: Have to wire the parameters set on Rastrigin and Sphere to the move evaluator
