Performs a [PMCMR::posthoc.friedman.nemenyi.test] for a [BenchmarkResult] and a selected measure. This means *all pairwise comparisons* of `learners` are performed. The null hypothesis of the post hoc test is that each pair of learners is equal. If the null hypothesis of the included ad hoc [stats::friedman.test] can be rejected an object of class `pairwise.htest` is returned. If not, the function returns the corresponding friedman.test. Note that benchmark results for at least two learners on at least two tasks are required.

([pairwise.htest]): See [PMCMR::posthoc.friedman.nemenyi.test] for details. Additionally two components are added to the list:
Whether the according friedman.test rejects the Null hypothesis at the selected p.value
Minimal difference the mean ranks of two learners need to have in order to be significantly different
