How to hook and execute custom code against store events

In past we saw this question from time to time where developers asking for the ability to intercept store events like Order Placed, Order Paid etc. The good news is, now it will be possiable to intercept all avilable event triggers in Gold R5 and upwards. We have incorporated the support to implement store event handling more like a service. Out of the box there is default event handling implemented and configured. In order to provide your custom handling you can create your cutom event handler by following certain rules and then can plug it in place of default one.
