#1669: First version with a simpler design as discussed with Michael Kommenda has been implemented and will be tested soon. Currently only the KotanchekFunction.cs is changed accordingly. Other benchmarks are going to follow soon.

The classes for the different distributions are not needed any longer. Static methods in RegressionBenchmark replace them.
