//  Class:      CSzBuffer
//
//  Purpose:    string buffer that automatically allocates space as needed
//
//  Interface:  Set        -- resets buffer to new string
//              Append     -- adds string (or number) to end of data
//              Prepend    -- adds string (or number) to front of data
//              GetData    -- gets pointer to string buffer
//              GetLength  -- gets length of string in buffer (in chars)
