Dictionary subclass enabling attribute lookup/assignment of keys/values.
For example::
>>> m = Settings({'foo': 'bar'})
>>> m.foo
'bar'
>>> m.foo = 'not bar'
>>> m['foo']
'not bar'
``Settings`` objects also provide ``.first()`` which acts like
``.get()`` but accepts multiple keys as arguments, and returns the value of
the first hit, e.g.::
>>> m = Settings({'foo': 'bar', 'biz': 'baz'})
>>> m.first('wrong', 'incorrect', 'foo', 'biz')
'bar'
