[EM] Recursive Elimination Supervisor

[Forest Simmons]

Tony,

here's a simpler version of the Recursive Elimination Supervisor,
based on a suggestion of yours.

Step 1.  Use the seed method in reverse to find the "Seed Loser" SL, from
among the N candidates.

Step 2.  While the SL sits out, recursively supervise the seed method to
find an N-1 stage recursive winner RW from among the N-1 remaining
candidates.

Step 3.  Compare SL and RW directly.  Whichever is better is the N stage
recursive winner. In case of a tie between these two, choose RW.
