In its current state, it is a working implementation that can be used to
explore the API. Bit patterns are missing and the masks are handled at the
iterator level rather than in the low level ufunc loops, so it isn't
particularly fast. IIRC, Mark was careful to leave some hooks for further
development and also set things up so that in the future masks could be
adapted to allow different mask values with different interpretations.
