 * \brief deinterleave an input block of samples into N outputs.

 *
 * \details
 * This block deinterleaves blocks of samples. For each output
 * connection, the input stream will be deinterleaved successively
 * to the output connections. By default, the block deinterleaves
 * a single input to each output unless blocksize is given in the
 * constructor.
 *
 * \code
 *   blocksize = 1
 *   connections = 2
 *   input = [a, b, c, d, e, f, g, h]
 *   output[0] = [a, c, e, g]
 *   output[1] = [b, d, f, h]
 * \endcode
