Changes

2017-11-03: Fixed bug in circles.py that output place names in files as lists instead of strings (['S','t','L','o','u','i','s'] instead of "St. Louis"). Changed vc_circles.py to call outjoiner.py automatically. Refactored vc_circles.py, circles.py, and outjoiner.py to put all of the configuration in vc_circles.py. Wrote out method to plot circles using ArcMap in [http://mcnair.bakerinstitute.org/wiki/Parallel_Enclosing_Circle_Algorithm here].

2017-10-30: Rechecked parts compatibility, switched PSU and case
