Can this be a const reference?

[sclittle, 2013/10/24 22:11:38]

Unfortunately, no. We need a non-const TopSites in order to call
top_sites->GetMostVisitedURLs, which is a non-const method.

+    : top_sites_(top_sites) {}
+MostVisitedURLsProvider::~MostVisitedURLsProvider() {}

typedef this in the interface.

Done.
