Parallelize SimilarityCalculators

Description

Similarity Calculators could be easily parallelized which would lead to nice performance improvements. This would make the diversity analyzers and algorithms that use similarity calculators faster. Because I'm not sure if it is ok to parallelize inside operators, I will just enclose the changes as patch.

Here are some measurements: Settings: GA/TSP, 30 generations, enabled PopulationSimilarityAnalyzer, 5 repetitions

  • a280, pop-size: 500: SpeedUp: 1.88
  • berlin 52, pop-size: 250: SpeedUp: 1.65

I assume the GP similarity calculators would also benefit quite a bit from this.

Add a flag ExecuteInParallel (check name) for diversity calculators. And hide it.
