#2332: refactored operators and analyzers

  • removed quality and maximization parameters in SingleObjectivePopulationDiversityAnalyzer
  • renamed SingleObjectivePopulationDiversityAnalyzer to PopulationSimilarityAnalyzer
  • added ConstrainedValueParameter for similarity calculators of analyzer
  • added ValueLookupParameter for similarity calculator of the following operators:
    • DuplicatesSelector, ProgressiveOffspringPreserver, ReferenceSetUpdateMethod, SolutionPoolUpdateMethod
  • removed some wiring code in specific problems
