flattenRing(...,CoefficientRing=>...) -- optionally specify the desired coefficient ring of the flattened ring

Description

i1 : k = toField (QQ[x]/(x^2+x+1));

i2 : R = k[y]/(x-y+2);

i3 : (S, f) = flattenRing(R); describe S

         k[y]
o4 = -----------
     - y + x + 2

i5 : (S2, f2) = flattenRing(R, CoefficientRing => QQ); describe S2

              QQ[y, x]
o6 = -------------------------
       2
     (x  + x + 1, - y + x + 2)
