default-env-file, default-env, and env-file now in place alongside env. default-env-file and default-env both use os.environ.setdefault so as not to overwrite existing variables (system environment) while env-file and env will overwrite existing variables. All four allow for multiple values (***How might this affect multiple default-env and default-env-file values, I expect that unlike env-file and env the first passed variables would win).
