// Use this class to wrap a pointer to a mapi buffer.  It will automaticly get 
// freed when it goes out of scope.  Use the instance of this just as you would
// its base type.  Example:
//     CMAPIBuffer< LPENTRYID>  lpeid;
//     HRESULT hr = HrMAPIFindDefaultMsgStore( m_pMAPISession, &cbeid, &lpeid);
//     hr = m_pMAPISession->OpenMsgStore( 0, cbeid, lpeid, ...
//
// The intended use of this class is for declaring mapi buffer pointers on the
// stack or inside of another class or structure.  There is NO value in creating
// an instance of this class on the heap with new().  It's sole purpose in life
// is to keep you from having to remember to free the buffer.
//
// If you need to reuse the pointer be sure to call MAPIFREEBUFFER before 
// reusing it.  Example:
//     CMAPIBuffer< LPENTRYID>  lpeid;
//     HRESULT hr = HrMAPIFindDefaultMsgStore( m_pMAPISession, &cbeid, &lpeid);
//     ... // Do some other work... 
//     MAPIFREEBUFFER( lpeid);
//     hr = HrGetSomeOtherEID( &cbeid, &lpeid);
