AHopkins review - create two environment files

Pulled from #1 (comment 597524)

Is this package meant to be used in Jupyter Notebooks or rather as a python package being imported and used in other python scripts? If the latter is the intended use, then I would recommend creating two environment yaml files: the first containing the bare minimum dependencies required to use the package (environment.yml, and the second a yaml file which includes packages like Jupyter which are not direct depenedencies of hyswap-geospatial-data-assembly (environment-docs.yml). It is bad form to included unnecessary and un-used python packages in the dependencies list; you want to keep the environment as small as possible.

@lstanish , @ehinman , @shamshaw - do we agree with this and should we create two environment files?
