FuncSubject

[fdecampredon]

I find the rx-react FuncSubject pretty useful, it can be used on every place that expect a callback and ease the pain of consuming event/stream source from third party api.
It's a very simple and tiny piece of code, so perhaps it's worth to be added into rxjs directly ?

@fdecampredon it might be although it is weird in that it doesn't have an error channel other than calling .onError...

For the usage with React onError was not needed, but we could imagine dispatching onError if the argument passed is an error instance.

Isn't Rx.Observable.fromCallback already filling this niche?
