[eadjzvay] App for jack and jill permutations

Create an app for assigning random matchings for jack-and-jill swing dance competitions, doing better (all permutations possible) than the "rotate N" method used nowadays.

Probably, leaders remember your original ordering, followers line up across from the partner you had previous round.

Avoid a pairing seen a previous round.  Avoid accidentally resetting to round 1.

Show hash of system seed. Input optional salt. Reveal system seed and use hash(salt||system seed) as the RNG seed.
