[EM] sequential dropping

[Markus Schulze]

Dear James Green-Armytage,

"sequential dropping" (SD) violates monotonicity.

Example (12 July 2000):

> Act I:
>
>    AB 18
>    BC 14
>    CD 12
>    DE 19
>    EF 15
>    FG 16
>    GA 11
>    DB 13
>    GE 17
>
>    SD chooses candidate A.
>
> Act II:
>
>    If "DE 19" is changed to "DE 10" then SD chooses
>    candidate D.
