InversionTest.InversionAnalysis.GradedPosetSequence:
An analysis of the inversion distribution of a graded poset This
can be used to analyze the reference sequence against a sorted
version of itself or against permutations of these elements in a
sequence passed in (which may be graded or not).
InversionTest.StatisticalTests.SystemReseededRandom:
Random number generator that randomly re-positions a standard MT
generator based on the system random entropy generator, so that any
permutation is theoretically possible.
