Feature #515
Fn to "flatten" muliple polynomial extns
Description
In C5 a user can easily create a ring like QQ[x][y] which is obviously isomorphic to QQ[x,y]. CoCoA can do many operations on elements of the second ring, but would be stuck given the first ring (e.g. factorization, sqfrfactor, gcd)
To make impl simpler have a fn which given a ring like QQ[x][y] produces a single-level poly extn together with two isomorphisms to move values back and forth.
We'd also need fn to tell whether a ring is a multiple poly extn.

Updated by Once this has been impl'ed (if), we should go back and finish those issues which needed the capability. See the related issues list!
