        "regulator of an elliptic curve"
        SYNTAX: X = reg(E1)
                X = reg(E2,P1,...,Pn)

        E1 is an expression whose value is an elliptic curve over Q.
        E2 is an expression whose value is an elliptic curve over the
        quadratic number field specified by curnf. P1,...,Pn are 
        expressions whose values are points over the quadratic number field 
        on the curve E2.
        
        X is assigned the regulator of E1 or the regulator of the points 
        P1,...,Pn on E2 respectively.

        
        Example 1: (correct)
                
                reg( EC( 1, 0, 0, 1, 2 ) )      

        Example 2: (correct)
                
                reg( EC( 0, NF(A), 0, 0, 6 ), PT(0,NF(A)), PT(0,-2*NF(A)) )
