*** We turn on the TWOMODULES mode
*** We turn on noncommutativity
Input the Maximum Degree you want to calculate
Input the number of the right  module variables
Input the number of the left  module variables
Now input all ring and then all module variables.
Right module variables should be before the left ones.
Input  the ring ideal and module relations in algebraic form  thus:
      vars v1, ..., vn;
       r1, ..., rm;
where v1, ..., vn are all the variables, and r1, ..., rm the  relations.
