        "Galois-field to polynomial"
        SYNTAX: X = gftopol(a)

        a is an expression whose value is a Galois-field element, a
        polynomial over a Galois-field, a matrix or a vector over
        these structures.
        
        gftopol transforms the structures over the Galois-field 
        into the corresponding polynomials over Z adding to the
        variable list the by curgf or curgf2bit specified variable.
        X is assigned the corresponding structure over polynomials 
        over Z.
        

        Example 1: (correct)

                gftopol(GF(3*A^2+A))

        Example 2: (correct)

                gftopol(GF(4*A+A^3+y))
