Since the compressor_stream are basically filter on top of other streams, 
the methods need to read from a stream output towards it. Hence,
the following could be done:

>void compress(InputIterator begin, InputIterator end, ostream& out);

without much problems. But I don't think I would get rid of the ostream.
