"smith set" is the smith set.
"schwartz set" is valid when the smith set and schwartz set differ.
When the smith or schwartz set are 1, a tabulator can test itself as
"condorcet-smith" or "condorcet-schwartz"
Other valid types of results are "tideman's alternative" (if schwartz = 1,
elect; else eliminate non-smith, runoff 1, repeat); "tideman's alternative
smith" (elects by smith set = 1); "tideman's alternative schwartz"
(schwartz set elimination); and "meek-stv".
This is an extremly basic outcome format. The json format.. I can't parse
