      This method allows for the use of git repositories to hold templates in addition to passing in a flat template file.

      - Parameter from: The string passed in from the command line
      - Returns: Returns the Path of the template file

      ## Important Notes ##
      1. template.yml file should be top level of the git repository
      2. template repositories will be downloaded to a .genesis folder in users home (~) directory
      3. Each download replaces prior versions of the template
