Changeset 9129 for branches/CMAES/HeuristicLab.Optimization/3.3/Interfaces

#1961:

• Changed CMA-ES to reference RealVector directly and work with that encoding only (separation of algorithm and encoding was not trivial to achieve)
• Simplified operator graph (also improves performance)
• Simplified strategy parameters (those used only during update are initialized in update)
• Added many termination criteria (same as in Hansen's Java version)
• Added different ways to calculate the mean (different weightings)
