   /**
   *  Wraps the source sequence in order to run its subscription and unsubscription logic on the specified scheduler. This operation is not commonly used;
   *  see the remarks section for more information on the distinction between subscribeOn and observeOn.

   *  This only performs the side-effects of subscription and unsubscription on the specified scheduler. In order to invoke observer
   *  callbacks on a scheduler, use observeOn.

   *  @param {Scheduler} scheduler Scheduler to perform subscription and unsubscription actions on.
   *  @returns {Observable} The source sequence whose subscriptions and unsubscriptions happen on the specified scheduler.
