+/*! \brief A rate 1/2, k=7 convolutional encoder for the CCSDS standard
+ * \ingroup ecc
+ *  
+ * 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.
