#2521:

• Refactored QuadraticAssignmentProblem to use new SingleObjectiveProblem
  • Removed QAPEvaluator
  • Adapted RobustTabooSearch
• Introduced several interfaces in PermutationEncoding necessary for wiring
• Changed all Encodings to use IItem instead of IOperator in ConfigureOperators (name still unchanged)
• Added a protected MaximizationParameter property in SingleObjectiveProblem (necessary for wiring)
• Changed AlleleFrequnencyAnalyzer to use ISolution interface instead of IItem
• Added a comment to ISolutionCreator<TSolution> of some changes that would be welcomed
