Changeset 5381 for trunk/sources/HeuristicLab.Encodings.RealVectorEncoding/3.3/RealVectorManipulator.cs

#1395

• Allowed to select the bounds checker to use in all RealVectorManipulator and RealVectorCrossover operators
• Added a second bounds checker, the ReflectiveBoundsChecker which does not cut at the bounds, but mirrors the vector at the bounds
• Use a repeating strategy in the move generators
• Removed obsolete IRealVectorPSODecoder and IRealVectorPSOEncoder interfaces
• Marked RealVectorToRealVectorEncoder as obsolete, internal and removed all meaningful code from it (it slipped into the release and should be thrown out as soon as possible)
• Use a repeating strategy to stick within the bounds in the StdDevStrategyVectorManipulator when manipulating the mutation strengths
• By default use smaller initial bounds in the StdDevStrategyVectorCreator (parameterized by the problem)
