Environment variable configuration loading class.

Using a class here doesn't really model anything but makes state passing (in a
situation requiring it) more convenient.

This module is currently considered private/an implementation detail and should
not be included in the Sphinx API documentation.

        Return a nested dict containing values from `os.environ`.

        Specifically, values whose keys map to already-known configuration
        settings, allowing us to perform basic typecasting.

        See :ref:`env-vars` for details.

        Examine config at location ``key_path`` & return potential env vars.

        Uses ``env_vars`` dict to determine if a conflict exists, and raises an
        exception if so. This dict is of the following form::

            {
                'EXPECTED_ENV_VAR_HERE': ['actual', 'nested', 'key_path'],
                ...
            }

        Returns another dictionary of new keypairs as per above.
