Addresses Issue #34.  Fixes a bug in which surrounding nodes but not the tip of interest were randomized.
Addresses Issue #34.   Adds test code for make_distance_based_randomizer.  The new code tests 5000 iterations of the randomizer to ensure all trees are seen.  The test also checks that results for each tree fall within the 99.9% CIs, and thus could occasionally fail.   The docstring explains the situation, so users know that only repeat failures across runs are of concern (but should in any case be rare).
Addresses Issue #34.  Removed a stray print statement.
