How to set up on idle event in MODO SDK.

/*
 * OnIdleVisitor is used to perform On Idle Event.
 * Evaluate() method will be called once the on idle event is registered.
 *
 * If you add more methods to this class and want to access them from outside this is how you need to do it:
 *  onIdleVisitorInstance.loc.method();
 * You get direct access to this class contents via '.loc'.
 * Don't ask me why ;).

     * Call this method when you want to arm on idle event.
     * Note that only one on idle event can be armed at a time.
     * This is why we disarm an event that was already there and arm new one.
     * In my code I make on idle event an event queue.
     * Each new event adds to the queue. This is to make sure that when on idle event happens
     * it will process all the events that happened up to the point the event is fired.
