-`complexFunc` is a function that returns the result of three simple, asynchronous functions `simpleFuncA()`, `simpleFuncB()`, and `simpleFuncC()`, which run concurrently. The completion handler is called only when all the simple functions have completed. Usage of this library has enabled the above clean interface. This can be scaled to much higher than three simple functions.

 Now you can create a `GroupWork`, and call `work.simpleFuncA()` on it like in the example.
 
-Caveats:
-  - notice that in each function, `start()` is called before each asynchronous task
-  - `finish(withResult:)` is called in the completion handler of each asynchronous task
-  - `start()` and `finish()` calls MUST be balanced
