// so I'm actually starting the effort for a better code base here in the tests
// i want to write down how you would use the very important instance type
// and then implement it to make it usable in this way
// how every mize based program to run on an os should create a mize instance
// opens the instance the way the user has configured (with env vars, build args, or config
// files)
// and we just call it "new()" and not "default_system()" so that it is clear that this is the
// method that should be used
let mize = MizeInstance::new();
// then the most important things you do with your mize instance is to get/set stuff
let name: MizeItem = mize.get("1/namespace");
let id = mize.new_item();

// or register update callbacks and update
//mize.on_update("5/name", |delta| println!(delta.new_value()));
//mize.update("5/name", "other-item")
// the goal is that also most things about the MizeInstance itself is controlled by
// get/set/update -ing values at the 0/ paths
