@mhevery I added this two methods `eventNameToAttrName` and `attrNameToEventName` here as static methods. I'm not sure if this is the best place (and way) to do this. These are just utility methods to transform event to attribute (and vice versa) when there's a long event (i.e. `on-some-really-long-event-name`/ `someReallyLongEventName`). What are your thoughts? any better places to put them?
