Use ExecutorService to Run Multiple Callable and Get Results In Order

Motivation

ExecutorService can run multiple Runnable/Callable, but there is no method for get their Results / Exception in order
(Similar to Promise.all in JavaScript)

So try to build a simple solution.

Simple Note

Test / Sample
  ConcurrentParallel.java
Implementation to Run Multiple Callable
  CallableParallelExecutor.java
Wrapper Class to wrap Callable
  CallableWrapper.java
