Performance improvements, timestamp enhancements; Version 2.6
o Elide some expensive debugging except for at higher log levels
o Avoid redundantly indexing expensive cpppo.dotdicts
o Replace a 'reduce' call (not avilable in Python3)
o Make all timestamp comparisions mathematical instead of string, and
  implement arbitrary (1-6 digit) precision and comparision epsilon.
o Add hisotry performance test, and outline tracemalloc support
o Major bug; timeit.default_timer is no longer a wall-clock time!  Use
  time.time/clock instead as appropriate for the platform.
