The first arg "name" is used by the as_view classmethod itself. Any
other argument that follows is used to instantiate the class.

https://github.com/pallets/flask/blob/0.10.1/flask/views.py#L73

The "name" is the name of the endpoint. You should always specifiy it.
It's the name you use, when you build URLs using the url_for() function.
