Separate hatfiledcmr egg into its own package

Currently the hatfield code is embedded into this project. To simplify the installation of this code recommend creating another repo with the hatfield code and building an automated build that will publish this code to pypi.

Will simplify the installation as we will no longer have to install a local egg package.

Start by locating where the hatfield code and local egg package are embedded in this project. Review how the package is currently installed, then determine the repository and automated PyPI publishing boundaries; done means hatfield is separately installable without installing a local egg.
