  | #### D.16.1.4 maximalGroebnerCone `Syntax:` `maximalGroebnerCone(` poly g `)` `maximalGroebnerCone(` ideal I `)` `Assume:` I reduced standard basis `Type:` cone `Purpose:` the euklidean closure of all weight vectors with respect to whom the initial form of g equals its leading term or the initial ideal of I equals its leading ideal. `Example:`
      LIB "gfanlib.so";
      ring r = 0,(x,y),dp;
      poly g = x+y+1;
      cone C = maximalGroebnerCone(g);
      rays(C);
      ==> 0,-1,
      ==> 1, 1

      ideal I = x2-y3,x3-y2-x;
      I = std(I);
      C = maximalGroebnerCone(I);
