PThreadWrappers return with the retval of called pthread. Task became an interface. WorkerThread moved to test_ThreadPool.hpp. Thread has stop() and m_isRunning members. ThreadPool is now Task and Thread type independent. No more assertions in PThreadWrappers. Unittests refactored. test dir cleaned up.
