| #### D.4.15.39 tensorModFreemod Procedure from library `modules.lib` (see modules_lib). Return: Tensorprodukt of M,F Example:
    LIB "modules.lib";
    ring R = 0,(x,y,z),dp;
    matrix a[1][2] = x,y;
    Matrix A = a;
    matrix b[1][2] = x2,y2;
    Matrix B = b;
    Module M = subquotient(A,B);
    M;
    ==> subquotient (| x y |, | x2 y2 |)
    ==>
    ==>
    FreeModule F = freeModule(R,3,0);
    F;
    ==>  3
    ==> R
    ==> free Module
    ==> Degrees of the generators: {0} {0} {0}
    ==>
    tensorModFreemod(M,F);
    ==> cokernel | 0 0 0 x 0 0 -y 0  0  |
