I am following along on this year old ui-router tutorial http://txt.fliglio.com/2013/05/angularjs-state-management-with-ui-router/ and I'm getting the following error:
Error: Could not resolve 'settings/quotes' from state 'settings' 
I am fitting this tutorial app into my Express.JS setup and I'm using Jade for my templates.
All the Jade templates seem to be rendering properly but I am noticing that there is no href being created for the User Quotes (settings/quotes URL) ui-sref link. Maybe there is a clue there. You can see this in the below screenshot:
I will post all key files below.
