-The signature is the same as `join` exept for the `resultSelector`. Now the result selector takes item from the left sequence and an observable of values from the right sequence. That observable will emit every right value that the left value is paired with. The pairing in `groupJoin` is symmetrical, just like `join`, but the contruction of results isn't. Instead of the way it is now, the argument of the `resultSelect` could just as well have been a single `GroupedObservable` with the left value as a key and the right values being emitted.

 Lets revisit our example from `join` where the windows on the left never close.
