Documentation examples no longer accurate

In swift 5

var cooldownRefreshedEvent = IZEvent<Void>()

now requires explicitly specifying void type when posting the event:

cooldownRefreshedEvent.post(())

and can no longer be assigned to a parameterless target:

init() {
    reminder.cooldownRefreshedEvent
        .register(self, function: MyTableViewController.handleCooldownRefresh)
}

func handleCooldownRefresh(_ x: Void) {
    reloadModel()
}
