Feature: add an observable

[no-more]

Hi,

Do you think it could be possible to add an observable which could be subscribed in order to retrieve and use all logging events in another component?
Of course no need to store an history of the events, just emit on the observable each time a new log request occurs.
This would require to have a global service available across all the instances of the logger, I don't know if it's possible for you to do such a thing.

Thanks a lot.
