/**
* Projects each notification of an observable sequence to an observable sequence and merges the resulting observable sequences into one observable sequence.
* @param {Function} onNext A transform function to apply to each element; the second parameter of the function represents the index of the source element.
* @param {Function} onError A transform function to apply when an error occurs in the source sequence.
* @param {Function} onCompleted A transform function to apply when the end of the source sequence is reached.
* @param {Any} [thisArg] An optional "this" to use to invoke each transform.
* @returns {Observable} An observable sequence whose elements are the result of invoking the one-to-many transform function corresponding to each notification in the input sequence.
