[alltheseas]

User Story

As a pleb using Damus who would like to test a question with the other plebs, I would like to create a (free) poll, so that I can learn the preference and sage wisdom of the plebs.

Acceptance Criteria

1. Pleb has capability to create a poll that allows pleb to specify a single question, and
2. Poll has two (2) to four (4) choices, and
3. Poll sports a default time out timer of 144 blocks (approximately 24 hours in fiat time), and
4. Time out timer is displayed (12 hours remaining til poll close), and
5. Poll does not show results prior to voting (as not to influence the independent judgment of the plebs), and
6. Poll contains answer counter ["55 plebs have voted"], and
7. Upon expiration of timer, poll is labeled "finished", and results are displayed [A: 80%; B: 16%; C: 3%; D: 1%]
