stupid question: Why is imshow in io module?

[Juan Nunez-Iglesias]

@Josh, there's two issues here: whether the import io is wasteful (which,
as you demonstrated, it isn't), and whether it makes sense to stick imshow
under io, which is certainly not clear to me, despite the rationalisations
posted to this thread. =P

I would argue that we rename the "viewer" package to "view" and include a
simple imshow in there *in addition to* the viewer.

Juan.
