Add a class comment.

Done.

+@property(nonatomic, retain) UIButton* reloadButton;

Each property needs a comment. Is it expected that every instance of the cell
class will have more than one of these as non-nil properties?

Are you asking because of nullability annotations? I could add those too, not
sure if we prefer to use macros or annotate each of them (These should never be
null).
I'm also using strong instead of retain to make it more "ARCy".
