    with_user_roles(roles)

    It allows to check if a user has access to a view by adding the decorator
    with_user_roles([])

    Requires flask-login

    In your model, you must have a property 'role', which will be invoked to
    be compared to the roles provided.

    If current_user doesn't have a role, it will throw a 403

    If the current_user is not logged in will throw a 401
