this shouldn't be in the header, but you'll probably need it in
app_list_view_controller.mm with the comment below

[calamity, 2013/08/14 09:19:00]

Done.

 namespace app_list {
 class AppListMenu;
 class AppListViewDelegate;
 class SearchBoxModel;
 class SearchBoxModelObserverBridge;

Objective-C functions "can't" return references.. (they kinda can, but it breaks
some assumptions). Probably nicest is if these return an NSString* instead, and
the conversion is done in the AppListViewController

Done.
