pub fn get_load_state<'a>(&self, cx: Scope<'a>) -> &'a RcSignal<RouterLoadState> {
        create_ref(cx, self.load_state.clone())
    }
Gets the load state of the router. You'll still need to call `.get()`
after this (this just returns a `&'a RcSignal` to derive other state
from in a `create_memo` or the like).
