    * This uses 'SubSink' library to achieve this.

    * @important Please keep a note that if you happen to implement OnDestroy in your component,
    * you have to explicitly call super.ngOnDestroy() to invoke un-subscription for the component.
    * @param sub; Subscription list. Assign your subscriptions in your component to 'sub'
