package observables
Contains special Observables.
In Scala, this package only contains rx.lang.scala.observables.BlockingObservable.
In the corresponding Java package rx.observables, there is also a
GroupedObservable and a ConnectableObservable, but these are not needed
in Scala, because we use a pair (key, observable) instead of GroupedObservable
and a pair (startFunction, observable) instead of ConnectableObservable.

BlockingObservable
[+T] extends AnyVal
An Observable that provides blocking operators.
An Observable that provides blocking operators.
You can obtain a BlockingObservable from an Observable using rx.lang.scala.Observable.toBlocking

ConnectableObservable
[+T] extends Observable[T]
A ConnectableObservable resembles an ordinary Observable, except that it does not begin emitting items when it is subscribed to, but only when its connect method is called.
A ConnectableObservable resembles an ordinary Observable, except that it does not begin emitting items when it is subscribed to, but only when its connect method is called. In this way you can wait for all intended Subscribers to subscribe to the Observable before the Observable begins emitting items.
