| #### D.4.25.12 getSmallest Procedure from library `normal.lib` (see normal_lib). Usage: getSmallest(J); J is an ideal. Return: the generator of J of smallest degree. If there are more than one, it chooses the one with smallest number of monomials. Note: It looks only at the generator of J, not at all the polynomials in the ideal. It is intended maninly to compute a good universal denominator in the normalization algorithms. Example:
    LIB "normal.lib";
    printlevel = printlevel+1;
    ring s = 0,(x,y),dp;
    ideal J = x3-y, y5, x2-y2+1;
    getSmallest(J);
    ==> x2-y2+1
    printlevel = printlevel-1;
