So I did the testdrive and the user crud. I then started my own app. I have a function I need executed that will return a value to be used in the footer, so it should be executed for any page (it checks data cache first).
There's no __construct() in the sitecontroller, so I put the call to the function before each render there. But now I've added a model, and the function doesn't get called by usercontroller, and I really don't want to start adding it before all those renders too. Where would an initialization function go?
