34 * \brief Maps elements from a set of input vectors to a set of output vectors.

37 * \details
38 * If in[i] is the input vector in the i'th stream then the output
39 * vector in the j'th stream is:
40 *
41 * out[j][k] = in[mapping[j][k][0]][mapping[j][k][1]]
42 *
43 * That is mapping is of the form (out_stream1_mapping,
44 * out_stream2_mapping, ...) and out_stream1_mapping is of the
45 * form (element1_mapping, element2_mapping, ...) and
46 * element1_mapping is of the form (in_stream, in_element).
