Un tipo de Sujeto que requiere un valor inicial y emmite su valor actual cuando es suscrito

    class BehaviorSubject<T> extends Subject {

      get value: T
      _subscribe(subscriber: Subscriber<T>): Subscription
      getValue(): T
      next(value: T): void

      lift<R>(operator: Operator<T, R>): Observable<R>
      next(value?: T)
