    Securing an Eve-powered API with Basic Authentication (RFC2617).

    This script assumes that user accounts are stored in a MongoDB collection
    ('accounts'), and that passwords are stored as BCrypt hashes. All API
    resources/methods will be secured unless they are made explicitly public
    (you can open to public access one or more resources and/or methods by
    toggling some API settings - see docs).
    
    You will need to install py-bcrypt: ``pip install py-bcrypt``

    This snippet by Nicola Iarocci can be used freely for anything you like. 
    Consider it public domain.
