[EM] AERLO definition for ERBucklin & ERIRV. Yes ERBucklin needs AERLO for Strong FBC

[MIKE OSSIPOFF]

For methods that aren't pairwise-count methods, this is what AERLO is:

The voter may designate a line in hir ranking, to indicate that if no one 
above that line wins, then that voter wants to promote to 1st place all of 
hir above-line candidtates, and have the ballots counted again.

This is done for all ballots having an automatic equal ranking line, and, 
when that has been done, there's only one recount, after the parageraph 
before this has been carried out for all rankings having an automatic equal 
ranking line with no winners above it.

(For pairwise-count methods, such as Condorcet, there's an additional 
requirement for the promotion: It only takes place for a particular ranking 
if there's a cycle with members above and below that ranking's AERLO line. 
That avoids unnecessary promotions in those methods).

Yes, as I was saying in an earlier posting, ERBucklin(whole) meets FBC, but 
not Strong FBC. To meet Strong FBC, that method needs AERLO.

For rank methods, AERLO makes FBC compliance into Strong FBC compliance, and 
makes WDSC compliance into SDSC compliance.
