/////////////////////////////////////////////////////////////////////
// threadwrapper.h CThreadWrapper class.
//This base class is used to derive thread based objects that will have their
//own event loop running in this worker thread. The init() function is called by
// the worker thread when started to setup all signal-slot connections
//The ThreadExit() function is called by the thread after CleanupThread() is
//called. This can be used in cases where the worker thread must delete its own resources
// as is the case for network objects.
// History:
// 2013-10-02 Initial creation MSW
