* Maps values from the source to a specific observable, and merges them together in a serialized fashion.

|
|
* @param {Observable} observable the observable to map each source value to
|
|
* @param {function} [resultSelector] an optional result selector that is applied to values before they're
|
|
* merged into the returned observable. The arguments passed to this function are:
|
|
* - `outerValue`: the value that came from the source
|
|
* - `innerValue`: the value that came from the projected Observable
|
|
* - `outerIndex`: the "index" of the value that came from the source
|
|
* - `innerIndex`: the "index" of the value from the projected Observable
|
|
* @returns {Observable} an observable of values merged together by joining the passed observable
|
|
* with itself, one after the other, for each value emitted from the source.
