Concept: history match then frequency counting with non-seeded randomness
         - revised matching function (highest frequency match, not first)
         - testing findall, not finditer

[Reference] EbTech's "Boltzmann Counter," a variation on frequency counting, is 
            used when history fails. See http://www.rpscontest.com/entry/13015
