Getting comonad into base

[Sandy Maguire]

Ollie: It's for giving my own instances. I suspect most of the reasons that
comonads feel uninteresting is that they've been relegated to a
second-class citizen in the ecosystem.

chessai: I'm not proposing the whole package; just the class. I can't
imagine the migration path is any harder than putting an ifdef into the
comonads package.
