Link to timer example in helper libraries docs is 404

When the link is clicked, Github returns a page not found/404 notice.

I added several more timer examples, but I still need to push the pages, along with a LOT of documentation updates. As mentioned, check the example timer files. When using timers, I definitely suggest using the ScriptExecution.createTimer method, rather than the native Jython threading.Timer.
