Create a SlotDict constructor which can take an optional positional arg that
is passed to the update() method (similar to the dict constructor), and also
pass keyword arguments into the update() method if any are given. This makes
it possible to use the constructor similarly to the way that the
_emerge.SlotObject constructor is used.
