cartesianProd

Carries out the index calculation of Cartesian products of any number of arrays and returns the resultant product aside the indices

Cartesian product of any number of sets is a set of tuples in which, all possible tuples with elements of initial sets are included.

for example: if A={1 2 3} and B = {a b} then A*B = {(1,a),(2,a),(3,a),(1,b),(2,b),(3,b)};

This function calculates the indices of production and also the resultant array as a cell;
