ost::ThreadKey::ThreadKey()
       Create a unique thread specific container.

   virtualost::ThreadKey::~ThreadKey()[virtual]
       Destroy a thread specific container and any contents reserved.

       This class allows the creation of a thread context unique 'pointer' that can be set and retrieved and can
       be used to create thread specific data areas for implementing 'thread safe' library routines.

       Finally, Common C++ supports a thread-safe 'AtomicCounter' class. This can often be used for reference
       counting without having to protect the counter with a separate Mutex counter. This lends to lighter-
       weight code.

void*ost::ThreadKey::getKey(void)
       Get the value of the pointer for the thread specific data container. A unique pointer can be set for each
       execution context.

       Returns
           a unique void * for each execution context.

   voidost::ThreadKey::setKey(void*)
       Set the value of the pointer for the current thread specific execution context. This can be used to store
       thread context specific data.

       Parameters- ptr to thread context specific data.
