+/**
+ * Returns fake Now on Tap results for captions and thumbnails to make testing easier until
+ * the server returns real data.
+ * TODO(donnd): remove this throw-away code!

[Theresa, 2016/09/20 19:51:39]

The server code is getting close, right? How long will this throw away code be
used? Also, can the faked data be landed separately from the v1 parsing so that
it's easy to revert the CL?

[Donn Denman, 2016/09/20 21:16:36]

Great idea, I'll hopefully use this in the future!

For now I think we can just skip it altogether -- the server is getting close to
being ready and now that this code has been uploaded it will be easy to grab a
CL for just the fake server response.
