Incompatible with Python 3.x

[pfoppe]

This code base was developed in python 2.7 and mostly executed from an Esri ArcGIS Desktop (arccatalog/arcmap) or ArcGIS Server (10.3+) environment. This has not been developed to work with python 3.x (Esri ArcGIS Pro).

Creating an issue to bring visibility that this only works with python 2.7 and target an upgrade in the future to work with python 3.x (support ArcGIS PRO).
