C# Class SwarmOps.FitnessTraceQuartiles

Store fitness-values at intervals during optimization runs and write their quartiles to a file afterwards. This only supports a fixed number of optimization runs and iterations per run which must therefore be known in advance. Keep the number of intervals small because it requires much memory.

A matrix of fitness values is being stored and their quartiles computed after optimization.
