40 * Data is passed in as a vector of length \p vlen from multiple
41 * input sources. It will look through these streams of \p vlen
42 * data items and output two streams:
43 *
44 * \li Stream 0 will contain the index value in the vector where
45 * the maximum value occurred.
46 *
47 * \li Stream 1 will contain the number of the input stream that
48 * held the maximum value.
