| /*Dealing with three-level hierarchy: | |
| Feeds > Timeline > Article | |
| Primary (master) is nav controller with Feeds and Timeline. | |
| Secondary (detail) is nav controller with Article. | |
| I get a reference to primary and secondary navigation controllers when app is launching. | |
| Storyboard uses show segue for Feeds > Timeline. It uses showDetail segue for Timeline > Article. | |
| This is probably not the final version of this code for my app, but so far it's doing what I want.*/ | |
