Detailed Description

Maps elements from a set of input vectors to a set of output vectors.

If in[i] is the input vector in the i'th stream then the output vector in the j'th stream is:

out[j][k] = in[mapping[j][k][0]][mapping[j][k][1]]

That is mapping is of the form (out_stream1_mapping, out_stream2_mapping, ...) and out_stream1_mapping is of the form (element1_mapping, element2_mapping, ...) and element1_mapping is of the form (in_stream, in_element).

Parameters:

item_size	(integer) size of vector elements
in_vlens	(vector of integers) number of elements in each input vector
mapping	(vector of vectors of vectors of integers) how to map elements from input to output vectors
