 * Description: CMPI C++ Provider Base class
 *              This class must be instatiated once per C++ CMPI style provider.
 *              It maintains the broker and oneTime variables on a per provider
 *              basis and allows CmpiImpl to be used as a DLL.
 *              Use the CMProviderBase macro instantiate this class and the 
 *              static variables.
