The Pynuts class no more inherits from flask.Flask
The Pynuts class no more inherits from flask.Flask

All flask.Flask arguments are removed from the Pynuts __init__
method.
The only argument left is `app`, a Flask application.
This argument will be stored as self.app. Thus, the application
configuration and methods will be accessible through a Pynuts
instance.
