| #### D.6.9.1 coDimMap Procedure from library `classifyMapGerms.lib` (see classifyMapGerms_lib). Usage: coDimMap(I, #); I=ideal, #=list Compute: a bound of the A-determinacy of the map germ defined by I. Return: a list in which 1st entry gives the bound of the A-determinancy and the second entry gives the codimension of the map germ defined by I. Note: if # is empty it computes A^e-codimension(the extended codimension). Example:
    LIB "classifyMapGerms.lib";
    ring R=0,(x,y),(c,ds);
    poly f1=x;
    poly f2=xy+y5+y7;
    poly f11=f1+f2*f1;
    poly f22=f2+f1^2;
    map phi=basering,x+y,y+y2;
    f1=phi(f11);
    f2=phi(f22);
    ideal I=f1,f2;
    coDimMap(I);
