Placeholder meta-issue for possible "polling" features

One possible use of the database is for polling populations. This issue was created to discuss and record possible features to support polling.

Under the current model, a poll would be a document with associated propositions. True/False questions can be simple propositions.

Multiple choice polls could be done using template predicates. In such a case, we would need a way to only allow a user to vote on one for the versions of the template predicate.

Possible features

• Temporarily hiding results of a vote during a polling period to prevent it from influencing votes.
• Various statistical calculations related to vote counts and potential vote population (e.g. statistical significance)
• Automated generation of all the propositions/template predicates from a "normal" poll document.
