Kolmogorov-Smirnov uniformity test on the p-values for best individual.

* Best individual from the population is evaluated on new test vectors, p-value is stored to the vector for further processing.
* Vector of p-values is tested for uniformity with KS test.
* In random-random scenario, pvalues should be uniformly distributed (self-test).
