        "affine to projective"
        SYNTAX: X = aftopr(P1)

        P1 is an expression whose value is an affine point on an 
        elliptic curve.

        X is assigned the corresponding projective point.


        Example 1: (correct)

                aftopr(NF(PT(0, 3)))


        Example 2: (correct)

                aftopr(O)


        Example 3: (correct)

                aftopr(PT(GF(3*A),1))


        Example 4: (incorrect)

                aftopr(PT(0, 3, 1))
