Dan Horrigan (Eric Barnes) Events Library - Help?

[eluser]Devon Lambert[/eluser]
Hello all,

Trying to make use of this events library made by Dan Horrigan, and Eric Barnes.
https://github.com/dhorrigan/codeigniter-events

Unfortunately, I cannot figure out how to properly incorporate it in my code to listen/trigger events.

Can someone point me in the direction of a quick example of usage?

Thanks.
