nit: nuke one empty line

[rkc, 2013/09/04 23:48:02]

Done.

+namespace {

+const int kIconSize = 32;

[xiyuan, 2013/09/04 23:15:41]

We probably should move this to a common place to share with WebstoreResult.

[rkc, 2013/09/04 23:48:02]

As of now there didn't seem like a good place to put this, since we don't have a
common file for the result classes. I'll get this in the next set of
refactoring; we still need to move stuff from tests also into common.

[xiyuan, 2013/09/04 23:15:41]

Is |interaction_rank_| in range [0,1]? Relevance needs to be within that range
to make the Mixer happy.

[rkc, 2013/09/04 23:48:02]

Yes, interaction rank is in the range of 0-1.
