    /*! \brief A rate 1/2, k=7 convolutional encoder for the CCSDS standard
     * \ingroup error_coding_blk
     *
     * \details
     * This block performs convolutional encoding using the CCSDS standard
     * polynomial ("Voyager").
     *
     * The input is an MSB first packed stream of bits.
     *
     * The output is a stream of symbols 0 or 1 representing the encoded data.
     *
     * As a rate 1/2 code, there will be 16 output symbols for every input byte.
     *
     * This block is designed for continuous data streaming, not packetized data.
     * There is no provision to "flush" the encoder.
