* \b Overview
*
* Takes the conjugate of a complex unsigned char vector.
*
* <b>Dispatcher Prototype</b>
* \code
* void volk_gnsssdr_16ic_conjugate_16ic(lv_16sc_t* cVector, const lv_16sc_t* aVector, unsigned int num_points);
* \endcode
*
* \b Inputs
* \li aVector: Vector of complex items to be conjugated
* \li num_points: The number of complex data points.
*
* \b Outputs
* \li cVector: The vector where the result will be stored
