  3. * Returns an Observable that mirrors the source Observable with the exception of an `error`. If the source Observable
  4. * calls `error`, this method will resubscribe to the source Observable for a maximum of `count` resubscriptions (given
  5. * as a number parameter) rather than propagating the `error` call.

  9. * Any and all items emitted by the source Observable will be emitted by the resulting Observable, even those emitted
  10. * during failed subscriptions. For example, if an Observable fails at first but emits [1, 2] then succeeds the second
  11. * time and emits: [1, 2, 3, 4, 5] then the complete stream of emissions and notifications
  12. * would be: [1, 2, 1, 2, 3, 4, 5, `complete`].

  14. * @return {Observable} The source Observable modified with the retry logic.
