+ *
+ * Maps each source value to the given Observable `innerObservable` regardless
+ * of the source value, and then merges those resulting Observables into one
+ * single Observable, which is the output Observable.
+ *
+ * @example <caption>For each click event, start an interval Observable ticking every 1 second</caption>
+ * var clicks = Rx.Observable.fromEvent(document, 'click');
+ * var result = clicks.mergeMapTo(Rx.Observable.interval(1000));
+ * result.subscribe(x => console.log(x));

+ * @param {ObservableInput} innerObservable An Observable to replace each value from
+ * the source Observable.
+ * @param {function(outerValue: T, innerValue: I, outerIndex: number, innerIndex: number): any} [resultSelector]
+ * A function to produce the value on the output Observable based on the values
+ * and the indices of the source (outer) emission and the inner Observable
+ * emission. 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
+ * @param {number} [concurrent=Number.POSITIVE_INFINITY] Maximum number of input
+ * Observables being subscribed to concurrently.
+ * @return {Observable} An Observable that emits items from the given
+ * `innerObservable` (and optionally transformed through `resultSelector`) every
+ * time a value is emitted on the source Observable.
+ * @method mergeMapTo
+ * @owner Observable
