| #### D.14.2.18 disp_zdd Procedure from library `polybori.lib` (see polybori_lib). Usage: disp_zdd(ss); zero-supressed decision diagram ss Return: string containing visualization of ss Note: the resulting string is the visualization of the polynomial that corresponds to ss, but with a additional structure that comes from the zdd. Every reached else- Branch induces a new line in the string. Example:
    LIB "polybori.lib";
    ring r1=0,(x,y,z),Dp;
    poly f1=xyz+xy+xz+yz+y+z+x+1;
    zdd s1=f1;
    disp_zdd(s1);
    ==>  x1(x2(x3+1)+
    ==>        x3+1)+
    ==>     x2(x3+1)+
    ==>        x3+1
    ring r2=0,x(1..6),Dp;
    poly f2=x(1)+x(2)+x(3)+x(5)^2+x(6);
    zdd s2=f2;
    disp_zdd(s2);
    ==>  x1+
    ==>     x2+
    ==>        x3+
    ==>           x5+
    ==>              x6
    ring r4=0,x(1..6),Dp;
    poly f2=x(1)+1;
    zdd s2=f2;
    ==> // ** redefining s2 **
    disp_zdd(s2);
    ==>  x1+1
    ring r2=0,x(1..6),Dp;
    ==> // ** redefining r2 **
    poly f2=x(1)*x(2)*(x(3)-x(5)^2*x(6))+3*x(4)*x(5)-3;
    zdd s2=f2;
    ==> // ** redefining s2 **
    disp_zdd(s2);
    ==>  x1(x2(x3+
    ==>           x5(x6)))+
    ==>     x4(x5)+1
    poly f4=0;
    zdd s4=f4;
    disp_zdd(s4);
    ==> 0
    poly f5=1;
    zdd s5=f5;
    disp_zdd(s5);
    ==> 1
