Maybe we should be using url::Origins here, rather than pairs of strings?  (GURL
is also an option, but I'd prefer not to allow granting of individual URLs with
paths unless we need to.)

On that note, perhaps it should be called GrantOrigin.

Done and done.

[Charlie Reis, 2015/09/23 00:07:15]

Please use url::Origins rather than strings (same in the impl file).

[paulmeyer, 2015/09/23 17:03:54]

Sorry, I misunderstood. Now using url::Origin.

Same style nit.

[paulmeyer, 2015/09/22 22:13:57]

Done.
