Set the landing page to root `/`

[pasqLisena]

When I try to setup swagger to serve the UI from root / (rather than /api/docs):

api_doc(app, config_path='swagger.yml', url_prefix='', title='API title')

I get the following error:

I don't get this with aiohttp. But I get a different error #22

@pasqLisena This is Flask requirements, you should set url_prefix non-empty, It has nothing to do with this project.
