        "basis of the Mordell-Weil group"
        SYNTAX: X = basismwg(E)

        E is an expression whose value is an elliptic curve over Q.
        
        The basis of the Mordell-Weil group is computed and displayed
        on the screen. 
        X is assigned the rank of the Mordell-Weil group of E.
        If the rank is greater than 0, the basis points are stored
        in AV (see "? avfunc").

        For HEIGHTBOUND see ? ecfunc.

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