| ##### 7.7.8.0. mod2str Procedure from library `freegb.lib` (see freegb_lib). Usage: mod2str(M[,n]); M a module, n an optional integer Return: string Purpose: convert a module into a polynomial in free algebra Note: if an optional integer is not 0, stars signs are used in multiplication Example:
    LIB "freegb.lib";
    ring r = 0,(x,y,z),(dp);
    module M = [1,x,y,x,y],[-2,y,x,y,x],[6,x,y,y,x,y];
    mod2str(M);
    ==> xyxy-2yxyx+6xyyxy
    mod2str(M,1);
    ==> x*y*x*y-2*y*x*y*x+6*x*y*y*x*y
