Hi Joel,

thanks for making this event emitter.
Could You think of an real world example, where You really see neol shine? It has not to be much code. But some more lines or explanation than the one example in the Readme.md.

Thanks!

Everytime a listener is registered, and EventListenerManager is returned, this is the item that contains .replay and thus allows the following.

noel.on('myEvent', listener).replay();

This class contains another method remove() which removes the event listener.

In the case that we want to return a remover for the event in the form of a function we currently need to do something like

const eventListenerManager = noel.on('myEvent', listener);
return () => eventListenerManager.remove();

or event worse

return noel.on('myEvent',listener).remove.bind(noel);

This could be simplified by adding a new function

noel.on('myEvent',listener).removeFn()

This function will return a function that when called will remove the listener.

This also allows for the service/item having the Noel instance to control whether the event should be replayed or not, returning the deleteFn when the latter is desired.
