I don't think we should add a new file for every utility function

[please use gerrit instead, 2014/03/22 01:34:30]

This function is shared between address_data.cc and address_ui.cc. Where do you

[Evan Stade, 2014/03/24 15:46:07]

in a util file

[please use gerrit instead, 2014/03/24 18:20:58]

Done.
