Is there a way to either register for alerts or query for changed items?

```

Can you use this library to register for alerts (when a page in a subsite is 
updated) or query for all changed pages since a certain timestamp?

I looked in the doc but did not see anything similar to this.

Thanks for any tips or pointers,

Jay
