Basic time period checking library

Period is a basic time period checking library. Period is based on period.py by William S. Annis. (available at https://www.biostat.wisc.edu/~annis/creations/period.py.html) and ported to python3 with a few improvements. Period.py was in part inspired by perl's Time::Period module and the time class mechanism of Cfengine.
