Description
NSGA-III is originally developed for problems with >3 objective, but is also an improvement over NSGA-II even for problems with 3 objectives. There exists a unified version of NSGA-III (U-NSGA-III) that can be applied to problems with any number of objectives which is probably interesting to implement in HL.

r17551: Create NSGA3 plugin.
r17557: Add parameters for algorithm.
r17558: Generate structured reference points and show them in Results tab.
r17559: Initialize and analyze solutions of first generation.
r17615: The list of Reference Points are now a storable field in the NSGA3 class.
r17616:
- Implement the first part of NSGA3.
- Solutions are saved in a List.
- Minor changes in Utility.cs.
- The reference points and the fronts are no longer stored.
- Minor restructuring in NSGA3.
