Win 7 environment setup

[Sebastian Cheung CQF]

Hi how to setup ENV_SETTINGS_FILE in Win 7? Thanks

In startup/create_app.py/create_app:

env_settings_file = os.environ.get('ENV_SETTINGS_FILE', 'env_settings_example.py')
app.config.from_pyfile(env_settings_file)

this needs to change to env_settings.py outside project directory as well?
