+ Decoder can use (*inSize) to check that stream was decoded correctly.
+ Some decoder in 7-Zip check it, if (full_decoding mode was set via ICompressSetFinishMode)
+ }
+
+ If it's required to limit the reading from input stream (inStream), it can
+ be done with ISequentialInStream implementation.

+ Decoder unpacks no more than (*outSize) bytes.
+ }

+ (progress == NULL) is allowed.
+
+
+ Decoding with Code() function
+ -----------------------------
+
+ You can request some interfaces before decoding
+ - ICompressSetDecoderProperties2
+ - ICompressSetFinishMode
+
+ If you need to decode full stream:
+ {
+ 1) try to set full_decoding mode with ICompressSetFinishMode::SetFinishMode(1);
+ 2) call the Code() function with specified (inSize) and (outSize), if these sizes are known.
+ }
+
+ If you need to decode only part of stream:
+ {
+ 1) try to set partial_decoding mode with ICompressSetFinishMode::SetFinishMode(0);
+ 2) Call the Code() function with specified (inSize = NULL) and specified (outSize).
+ }
+
+ Encoding with Code() function
+ -----------------------------
+
+ You can request some interfaces :
+ - ICompressSetCoderProperties - use it before encoding to set properties
+ - ICompressWriteCoderProperties - use it before or after encoding to request encoded properties.
+
+ ICompressCoder2 is used when (numInStreams != 1 || numOutStreams != 1)
+ The rules are similar to ICompressCoder rules
