//
// ThreadedMatrixMult is a class that extends QThread and implemenents a 
// matrix multiplcation operation within the run() method. 
//
// The run() method can be invoked by either calling start(), which causes the run() 
// routine to be executed in a separate thread, or by calling run(() directly which causes
// the routine to be executed in the current thread. 
//
// When run() is executed in a separate thread, the stop() method can be called
// by code executing in another thread. The stop() routine sets the member variable 
// haltFlag, which induces the run() routine to halt computation and return. 
//
// The terminate() member function is not used to stop the execution.
