class AliHLTHuffmanNode: public TObject

 assign code to this node loop to right and left nodes
 the decoding always has to start from the least significant bit since the
 code length is variable. Thats why the bit corresponding to the parent node
 has to be right of the bit of child nodes, i.e. bits correspond to the
 current code length. For storage in a bit stream however, bits are stored
 in a stream from MSB to LSB and overwrapping to the MSBs of the next byte.
 Here the reverse code is needed and the word of fixed length read from the
 stream needs to be reversed before decoding.
 Note: by changing the AliHLTDataDeflater interface to write from LSB to MSB
 this can be avoided.
