//! Qt Object interface to rest of UCC work to allow Qt Thread use
/*!
* \file UCCWorker.cpp
*
* This file encapsulates Qt implementation details and dependencies
* so that the rest of UCC is relatively unchanged.
*
* ADDED to UCC 2015_12 release by Randy Maxwell
*   Changes started on 2015_12_03
*   Changes  ended  on 2015_12_05
*   Addition of Multithreading performance enhancement feature
*		Example: UCC -threads 4 (to have 4 worker threads)
