Why the namespace? (For things in //chrome, you don't need a namespace, and with
the class the namespace is a bit redundant.)

Done.

This isn't necessary if you include the header file.

[May, 2016/02/09 17:38:53]

Done.

I think these can be private

[May, 2016/02/09 17:38:53]

Done.

Make this a static class method?

Done.
