  | #### D.6.7.3 gmscoeffs Procedure from library `gmssing.lib` (see gmssing_lib). Usage: gmscoeffs(p,K); poly p, int K Assume: basering constructed by gmsring Return:
      list l;
        matrix l[1];  C[[s]]-basis representation of p mod s^(K+1)
        ideal l[2];  p==matrix(gmsbasis)*l[1]+l[2]
Note: computation can be continued by setting p=l[2] Example:
    LIB "gmssing.lib";
    ring R=0,(x,y),ds;
    poly t=x5+x2y2+y5;
    def G=gmsring(t,"s");
    setring(G);
    list l0=gmscoeffs(gmspoly,0);
    print(l0[1]);
