Much Speedier TreEvo: Now Using phylolm, not geiger!

And much better test coverage! And documentation! And it is a stable build that passes Travis CI, and all its dont-run examples pass when tested locally, too! The best real release of TreEvo yet, because well... its the first real release, more or less!
